nfsd4: Handle the NFSv4 READDIR 'dircount' hint being zero

Browse source

RFC3530 notes that the 'dircount' field may be zero, in which case the
recommendation is to ignore it, and only enforce the 'maxcount' field.
In RFC5661, this recommendation to ignore a zero valued field becomes a
requirement.
