wlan: When RoamRssiDiff=0, Roam to any AP.

Currently, Setting RoamRssiDiff=0 does not ensure, STA roam to any AP.
There is one more check for RSSI lower than lookup threshold which
blocks roaming to any AP.
Hence, Move the IF check under RoamRssiDiff>0 so that when
RoamRssiDiff=0 is set, we roam to any AP
