Lukas Straub 161e603975 colo: Reuse the return path from migration on primary and secondary side ...

Use the return-path capability with colo and reuse the opened return path
file on both primary and secondary side.

This fixes a crash in colo where migration_cancel() races with colo closing
s->rp_state.from_dst_file.
