There is no need to do a ceph_pool_perm_check() on anything that isn't a
regular file, as the MDS is what handles talking to the OSD in those
cases. Just return 0 if it's not a regular file.

Looks good to me, thanks!
[ Took me a while to find when/where I reported that -- it was completely
swapped out from my memory! But I finally found it on my IRC logs. ]
Cheers,
