ceph: fix st_nlink stat for directories
Currently, calling stat on a cephfs directory returns 1 for st_nlink. This behaviour has recently changed in the fuse client, as some applications seem to expect this value to be either 0 (if it's unlinked) or 2 + number of subdirectories. This behaviour was changed in the fuse client with commit 67c7e4619188 ("client: use common interp of st_nlink for dirs"). This patch modifies the kernel client to have a similar behaviour.
