Revert "NFSv4/flexfiles: Abort I/O early if the layout segment was invalidated"

This reverts commit 8c74114ba2448979e4cb561ecc0720f7ce736895.
The mechanism for aborting I/O is racy, since we are not guaranteed that
the request is asleep while we're changing both task->tk_status and
task->tk_action.
