ceph: fix __dcache_readdir()
If directory is fragmented, readdir() read its dirfrags one by one. After reading all dirfrags, the corresponding dentries are sorted in (frag_t, off) order in the dcache. If dentries of a directory are all cached, __dcache_readdir() can use the cached dentries to satisfy readdir syscall. But when checking if a given dentry is after the position of readdir, __dcache_readdir() compares numerical value of frag_t directly. This is wrong, it should use ceph_frag_compare().
