knfsd: fix spurious EINVAL errors on first access of new filesystem
The v2/v3 acl code in nfsd is translating any return from fh_verify() to
nfserr_inval. This is particularly unfortunate in the case of an
nfserr_dropit return, which is an internal error meant to indicate to
callers that this request has been deferred and should just be dropped
pending the results of an upcall to mountd.
Thanks to Roland <devzero@web.de> for bug report and data collection.
