[PATCH] orinoco: Fix memory leak and unneeded unlock in orinoco_join_ap()

Signed-off-by: Pavel Roskin <proski@gnu.org>
Fix memory leak and unneeded unlock in orinoco_join_ap()

If orinoco_lock() fails, the code would still run orinoco_unlock(),
instead of freeing the allocated memory.  Found by sparse.
