Public bug reported:

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.
