qcacmn: Allocate hif_napi_info structures dynamically

Browse Source 
The hif_napi_info structure has a dummy netdev included.
The dummy netdev is large.  Avoiding unneeded allocation
save 30kb of memory.  Dynamically allocating the
hif_napi_info structures also reduces the size of
the contiguous memory needed for the parent structure.
