htt_tx_mutex, NBUF_QUEUE_MUTEX and HTT credit_mutex should all be
initialized before the related message handlers are connected to
their corresponding services, or there will be racing conditions
happening during WLAN driver initialization which will cause
the Linux kernel complaining for bad magic of spin locks and
triggers watch dog bite.

1) The htt htc free packet list is accessed without being protected
by a lock when packets are being removed from it, which may
introduce a potential racing condition during stability stress
test. Protect the list by htt tx mutex before any pakcets are freed
from it.
2) The same protection should be done to the htt htc packet misc
list.

When CONFIG_HL_SUPPORT is defined, htt_rx_dbg_rxbuf_init is not called,

be destroyed if it is not initialized.
Do not call htt_rx_dbg_rxbuf_deinit when CONFIG_HL_SUPPORT is defined.

When commands to Firmware fail during probe due to Firmware being down, in
most cases QDF_BUGs are hit, not allowing re-probing to take place. A new
API is defined to check if the failure is due to Firmware being down or not.
If so, return error gracefully allowing re-probing to take place

qcacld-2.0 to qcacld-3.0 propagation
With ATH_11AC_TXCOMPACT defined, host to target message send-completion
won't be called and messages are stored in htt_htc_pkt_misclist after
sending to HTC layer which will be freed upon htt_detach. This list
doesn't have a size limit and outgrow with more messages.
Add a fix to limit the size of this list which gives enough time for
firmware to process these messages before releasing it.

Some of the packets like configuration messages and ipa stat
messages to fw are added in htt misc list. If these packets
fail to be transmitted, they are added in endpoint tx queue as well.
When driver is unloaded, as these packets are present in misc list
as well as in endpoint tx queue, double free will happen and crash
will be observed.
Use magic pattern to distinguish the packets that are stored in
endpoint tx queue as well.

1) Remove reaping of Tx HIF buffers in Rx handling, instead handle

2) In ce_per_engine_service_fast check for more Rx packets after

3) Make stub functions as static inline for non-fastpath enabled case.
