vfs: patch for unpause()/revive() race condition

. unpause() and revive() can race - revive() can run during
  a device i/o unblock, causing two sendnb()s to occur, and the
  2nd one to fail
. this can easily happen when a process is blocking on tty and
  is then killed by a signal - tty cancels the i/o and then
  kills the process by a signal
