ceph: remove unused variables in ceph_mdsmap_decode()
Fix build warnings:
fs/ceph/mdsmap.c: In function ‘ceph_mdsmap_decode’:
fs/ceph/mdsmap.c:192:7: warning: variable ‘info_cv’ set but not used [-Wunused-but-set-variable]
fs/ceph/mdsmap.c:177:7: warning: variable ‘state_seq’ set but not used [-Wunused-but-set-variable]
fs/ceph/mdsmap.c:123:15: warning: variable ‘mdsmap_cv’ set but not used [-Wunused-but-set-variable]
Note that p is increased in ceph_decode_*.
