RDMA/cma: Refactor the inbound/outbound path records process flow
Refactors based on comments [1] of the multiple path records support
patchset:
- Return failure if not able to set inbound/outbound PRs;
- Simplify the flow when receiving the PRs from netlink channel: When
a good PR response is received, unpack it and call the path_query
callback directly. This saves two memory allocations;
- Define RDMA_PRIMARY_PATH_MAX_REC_NUM in a proper place.
