INI parameters parsing can fail because of fail to read INI file or
failed to parse at least one parameter. In some scenarios, driver should
assert if parsing is failed for atleast one INI parameter.
To differentiate these two failures, return different error status
values.

Currently the return type of qdf_queue_work is void,
whereas queue_work return type is bool denoting the status,
so changing the return type of qdf_queue_work to bool,
helps to check the status of the function.

The current print rate limiting for prints to console is
for all contexts.
There are some debug prints which come to console via work queues
which we don't want to rate limit and only rate limit coming via
interrupt context or bottom halves which causes
FW backpressure due to excessive prints.
So rate limit prints coming to console if in
interrupt context or bottom halves

spin_is_locked() provided by kernel has statement that we should not
rely heavily on the return value, it only tells that the spinlock is
seen to be locked, not that it is locked on your CPU.
Further, on CONFIG_SMP=n builds with CONFIG_DEBUG_SPINLOCK=n, the
return value is always 0.
So we should not use QDF_BUG to test/assert its return value, only be
used for debugging purpose.

Currently if the driver is in runtime suspend/suspending
state, any packet transmission will request for resume
via hif_pm_runtime_get.
Unfortunately there is a logging in the above API which
will lead to more time consumption in the NET_TX softirq
context. This can lead to other delay in processing other
softirqs in the system.
Fix this by skipping the logging in the packet transmission
path.

During nbuf free if entry is not found in debug tracker list
it is treated as double free or unallocated buffer free
which is not correct because there is possibility of nbuf

allocation failures for tracker nodes in system low memory state.

The existing QDF implementation does the following
1. The QDF trace either prints to the console
2. The QDF trace message is directed to the utils,
which based on log level
a. redirects to a user space daemon or
b. redirects to console
There is excessive logging detection in the utils code
before redirecting the prints to the console.
If the number of prints to console is more than
the configured threshold, we assert in development builds.
Moving the API for excessive logging detection from utils to
QDF trace.
The configuration for detection of excessive logging currently
is only for the number of prints per second.

The function qdf_ini_parse returns QDF_STATUS as SUCCESS even if no
fields are read from the ini file. Because of this even if the
ini file is corrupted and no values are read from it the function
still returns SUCCESS.
So, to avoid that and ensure that the ini file is not corrupted,
add a variable ini_read_count to count the number of fields read
from the ini file and return SUCCESS only if its value is not zero.
