Chuck Lever 53da7fe847 libfs: getdents() should return 0 after reaching EOD 
[ Upstream commit 796432efab ]

The new directory offset helpers don't conform with the convention
of getdents() returning no more entries once a directory file
descriptor has reached the current end-of-directory.

To address this, copy the logic from dcache_readdir() to mark the
open directory file descriptor once EOD has been reached. Seeking
resets the mark.
