libceph: fixup error handling in osdmap_apply_incremental()
The existing error handling scheme requires resetting err to -EINVAL
prior to calling any ceph_decode_* macro. This is ugly and fragile,
and there already are a few places where we would return 0 on error,
due to a missing reset. Follow osdmap_decode() and fix this by adding
a special e_inval label to be used by all ceph_decode_* macros.
