[PATCH] nfsd4: don't create on open that fails due to ERR_GRACE
In an earlier patch (commit b648330a1d741d5df8a5076b2a0a2519c69c8f41) I noted
that a too-early grace-period check was preventing us from bumping the
sequence id on open. Unfortunately in that patch I stupidly moved the
grace-period check back too far, so now an open for create can succesfully
create the file while still returning ERR_GRACE.
The correct place for that check is after we've set the open_owner and handled
any replays, but before we actually start mucking with the filesystem.
Thanks to Avishay Traeger for reporting the bug.
