NFS: Fix for bug in handling of errors for O_DIRECT writes
Commit eda3cef8dd2b83875affe82595db9d0c278879b2 ("NFS: Fix error
handling in nfs_direct_write_result()") ensured that if a WRITE returns
an error, then data->res.verf->committed is not tested (as it is not
initialised).
Then commit 60fa3f769f7651a60125a0f44e3ffe3246d7cf39 ("NFS: Fix two bugs
in the O_DIRECT write code") inadvertently reverted this while fixing
other problems.
So move the test so that we never examine ->committed in an error case,
and fix a speeling error while we are there.
