[PATCH] nfsd: fix spurious error return from nfsd_create in async case

Commit 6264d69 modified the nfsd_create()
error handling in such a way that nfsd_create will usually return
nfserr_perm even when succesful, if the export has the async export option.

This introduced a regression that could cause mkdir() to always return a
permissions error, even though the directory in question was actually
succesfully created.
