Change rereg_mr API between libibverbs and the provider's library
Currently, MR re-registration isn't implemented in libibverbs.
The only part which does exist is an API call between libibverbs
and the provider's library. Since there's no way for a user application
to invoke this API call, it's safe to assume it's unused.
Similarly to other verbs (for example, ibv_modify_qp), a modification
to the MR shouldn't change the user's handle. The current existing API is:
struct ibv_mr * (*rereg_mr)(struct ibv_mr *mr,
int flags,
struct ibv_pd *pd, void *addr,
size_t length,
int access);
As a result, this API call returns the exact same pointer it gets.
Instead, we propose retuning a status int, which is far more useful
than the current return value.
