[werror] Fix mismatched tags (struct vs. class) inconsistence

how about 'typedef struct CephContext ceph_context;' then? Yes, it is still exposing the type, but less visibly so. Or rename CephContext entirely, just like for ceph_mount_info.

It just feels like a step backwards to use void*. An opaque type like ceph_context gives at least _some_ chance to do static type checking, even in C.
