defconfig: wcnss: Enable wcnss pre-alloc memory

WLAN driver will use this pre-allocated memory (when available) for
large memory allocations; this will prevent WLAN driver load
failures because of the un-availability of the large size
slabs during module load. Enable support for pre-alloc memory for
WLAN driver on 8974.
