wilc1000: move 'deinit_lock' lock init/destroy inside module probe

Move initialization & deinitialization of 'deinit_lock' mutex lock inside
wlan_init_locks() & wlan_deinit_locks() API's respectively alongside other
locks. After the movement, the client count variable(client_count) which is
used for lock init/deinit is removed.
