qcacld-3.0: Fix pointer dereference condition

Browse Source 
In the API lim_perform_ft_pre_auth, the driver sends
a auth frame to a peer whose MAC address is extracted
from the session entry, and it may happen that the
pointer tpftPEContext is NULL, which results in
pointer dereference.

Fix is to send an auth frame only if the sFTPEContext
is valid.
