keys: Hoist locking out of __key_link_begin()

Hoist the locking of out of __key_link_begin() and into its callers.  This
is necessary to allow the upcoming key_move() operation to correctly order
taking of the source keyring semaphore, the destination keyring semaphore
and the keyring serialisation lock.
