NFSv4: Don't call nfs4_state_mark_reclaim_reboot() from error handlers
commit ae1007d37e00144b72906a4bdc47d517ae91bcc1 upstream.
In the case of a server reboot, the state recovery thread starts by calling
nfs4_state_end_reclaim_reboot() in order to avoid edge conditions when
the server reboots while the client is in the middle of recovery.
However, if the client has already marked the nfs4_state as requiring
reboot recovery, then the above behaviour will cause the recovery thread to
treat the open as if it was part of such an edge condition: the open will
be recovered as if it was part of a lease expiration (and all the locks
will be lost).
Fix is to remove the call to nfs4_state_mark_reclaim_reboot from
nfs4_async_handle_error(), and nfs4_handle_exception(). Instead we leave it
to the recovery thread to do this for us.
