NFSD: restore EINVAL error translation in nfsd_commit()

Browse Source 
commit 8a9ffb8c857c2c99403bd6483a5a005fed5c0773 upstream.

commit 555dbf1a9aac ("nfsd: Replace use of rwsem with errseq_t")
incidentally broke translation of -EINVAL to nfserr_notsupp.
The patch restores that.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
