qcacld-3.0: Split wlan.ko into wlan_resident.ko and wlan.ko

Browse Source 
Module is saved in specified memory location when loading. In some
third platform, after rmmod/insmod wlan.ko for a while, wlan.ko may
fail to load due to memory fragmentation.

Split wlan.ko into wlan_resident.ko and wlan.ko. Keep wlan_resident.ko
in kernel all the while and trigger insmod/rmmod only on wlan.ko.

wlan_resident.ko contains all the module realization while wlan.ko
only contains module init/exit.
