ceph: fix endianness bug in frag_tree_split_cmp
sparse says:
fs/ceph/inode.c:308:36: warning: incorrect type in argument 1 (different base types)
fs/ceph/inode.c:308:36: expected unsigned int [unsigned] [usertype] a
fs/ceph/inode.c:308:36: got restricted __le32 [usertype] frag
fs/ceph/inode.c:308:46: warning: incorrect type in argument 2 (different base types)
fs/ceph/inode.c:308:46: expected unsigned int [unsigned] [usertype] b
fs/ceph/inode.c:308:46: got restricted __le32 [usertype] frag
We need to convert these values to host-endian before calling the
comparator.
Fixes: a407846ef7c6 ("ceph: don't assume frag tree splits in mds reply are sorted")
