qcacld-3.0: Fix defects detected by Static code analyser

Browse source 
qcacld-2.0 to qcacld-3.0 propagation

Static code analyser detects uninitialized pointer/structure
access and dereferencing a pointer without null check.
As part of this fix host will initialize pointer/structure before
accessing it and put a null check for pointer access.
