qcacmn: Don't unregister WLAN_UMAC_COMP_IF_MGR during init

Currently WLAN_UMAC_COMP_IF_MGR is deregistered during
initialization of WLAN_UMAC_COMP_IF_MGR . During deinitalization
wlan_if_mgr_deinit tries to unregister WLAN_UMAC_COMP_IF_MGR which
may introduce errorneous behaviour as WLAN_UMAC_COMP_IF_MGR is already
unregistered.

Fix is not to unregister WLAN_UMAC_COMP_IF_MGR during initialization.
