af_unix: move unix_mknod() out of bindlock
Dmitry reported a deadlock scenario:
unix_bind() path:
u->bindlock ==> sb_writer
do_splice() path:
sb_writer ==> pipe->mutex ==> u->bindlock
In the unix_bind() code path, unix_mknod() does not have to
be done with u->bindlock held, since it is a pure fs operation,
so we can just move unix_mknod() out.
