wlan: Kernel Panic due to null pointer dereference.

Currently in csrIsSessionClientAndConnected function,
device mode is acessed from roamprofile without checking
if roamprofile exist or not.
As a part of fix added check to ensure that device mode
is obtained only when a valid roamprofile is available.
