qcacmn: Add buffer window for umac reset in progress

When the peer delete timer/vdev manager response timer expires, host checks
if the umac reset is in progress. If so, host will retrigger the timer.
It is possible that the umac reset is just completed and either of these
two timers got expired. In this case, host will assert saying that the peer
delete response/vdev manager response is not received from FW. FW may take
a few milliseconds to send the peer delete/vdev manager response to the
host after the umac recovery completes.

Hence, to avoid the crash, check if the umac reset was in progress during
the umac reset buffer window.

Add the below changes as well,
1) INI support to get the umac reset buffer window value.
2) Renamed the API dp_umac_reset_is_inprogress as
   dp_get_umac_reset_in_progress_state to return either
   CDP_UMAC_RESET_IN_PROGRESS or
   CDP_UMAC_RESET_IN_PROGRESS_DURING_BUFFER_WINDOW.
