qcacmn: Fix zero size malloc when memory debug is disabled
In SLUB disabled builds, the qdf_mem_malloc calls the
qdf_mem_malloc_fl function which doesn't
validate if the size provided is 0 and returns the value
ZERO_SIZE_PTR(((void *)16)) for the pointer. When this pointer
is dereferenced, it causes invalid address dereference.
Validate if the size parameter provided to qdf_mem_malloc is
0 or greater than QDF_MEM_MAX_MALLOC. Return failure if the
validation fails.
