Subject: [PATCH] qcacld-3.0: Avoid calling memory allocation function for
 allocation size 0

qcacld-2.0 to qcacld-3.0 propagation

Currently we are calling memory allocation function to allocate memory for
FT ies even though FT ies length is 0.
Due to above behavior we are seeing unnecessary memory allocation failure
error prints.
Change made to check for FT ies length before calling memory allocation
function.
