prima: NULL pointer validation for pHashTable

When deauth/disassoc is received from peer at the same time when
cleanup in progress because of disconnect from supplicant, there
is a chance that pHashTable can be NULL. Memory pointed by
pHashTable is freed during peDeleteSession, which is called during
cleanup. In dphLookupHashEntry, pHashTable is referenced without
any NULL check, which can lead to crash. Fix this by validating
pHashTable for NULL check.

Also, to resolve potential KW issue, added a NULL check in
__limProcessOperatingModeActionFrame before referencing sta context.
