qcacld-3.0: Rectify deinit sequence leading to NULL ptr dereference

In function hdd_wlan_de_init, the hdd_context is fetched via
cds_get_context. This context is then NULL checked. In the failure case
of this check, the hdd_context is still dereferenced which shall lead to
null pointer dereference.

Add proper jump statement to take care of the proper order of init and
deinit
