Bug Description
SRU Justification:
------------------
Impact:
-------
Observed firmware assert(non responsive state) just 2 min after connection.
Test case:
----------
1) Power up the device, Redpine modules are loaded by default, Nmcli initiates the connection and device starts background scan after connection. After 2-3 min issue will be replicated.
Result:
-------
Observed firmware assert while performing background scan.
Root cause analysis:
-------
There is a redundant null check for ssid info while preparing
probe request in background scan case, which blocks the probe request pkt
length update, leads to assert no-71(if probe-req-length is 0 or greater
the max probe length 120) in firmware.
Fix:
----
Removed the redundant null check.
Regression Potential:
-------
This is observed just 2 min after connection, fixed and checked the driver stability. Every thing ran smooth.
