qcacld-3.0: Fix psoc's use after psoc destroy

psoc is allocated during start module and destroy in stop modules.
due to this if psoc is used after stop modules it cause crash.
psoc should be the first thing to get allocated and last thing
to get destroyed.

Fix it by calling psoc destroy at the ned of the wlan exit and
allocating in wlan start.
