Trond Myklebust 8f174a208c nfsd4: Handle the NFSv4 READDIR 'dircount' hint being zero 
commit f2e717d655 upstream.

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.

Fixes: aee3776441 ("nfsd4: fix rd_dircount enforcement")
