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.
Adding time configuration also to detection of excess logging
to the console.

Handle skb fraglist creation if parent skb has nr_frags.
Currently it is being handled if parent skb has nr_frags
associated with it and results into acessing invalid skb
region.
e.g:
To understand example, consider below points:
1. Parent frag has 40 bytes of data(qdf_nbuf_data())
2. Assume each frag is of size 10 bytes.
----------------------------------------------------------
|Parent_SKB -----> 1st Fraglist SKB - Cons SKB chained |
----------------------------------------------------------
| nbuf->Data : 40B | Nbuf->Data: 0B |
----------------------------------------------------------
| Nr Frags: 16 | Nr Frags: 10 |
----------------------------------------------------------
| Data Len: 160B (16 * 10) | Data Len: 100B (10 * 10) |
----------------------------------------------------------
| Nbuf->len: 200B ( 40 + 160) | Nbuf->len: 100B |
----------------------------------------------------------
While creating fraglist,
Parent nbuf -> data_len will become 100 Bytes (Because of assignment '=').
Logically it should be (160B + 100B). '+='
This change incorporate above handling.
