Matt Turner 54e08dbe8f linux-user/xtensa: fix unlock of uninitialized frame pointer on sigreturn ...

If lock_user_struct fails, frame is uninitialized but the badframe
label unconditionally calls unlock_user_struct on it. Handle the
lock failure inline so badframe is only reached with a valid lock.
