Konstantin Belousov 4dec8579bd Fix the race while waiting for coveredvp lock during unmount. The vnode may ...

be recycled during the sleep, wrap the vn_lock with vhold/vdrop.
Check that coveredvp still points to the same mp after sleep (needed
because sleep dropped Giant).
Move check for user rights for unmount after coveredvp lock is obtained.
