nfsd: don't provide pre/post-op attrs if fh_getattr fails
nfsd calls fh_getattr to get the latest inode attrs for pre/post-op
info. In the event that fh_getattr fails, it resorts to scraping cached
values out of the inode directly.
Since these attributes are optional, we can just skip providing them
altogether when this happens.
