[PATCH v3 1/3] migration/rdma: Fix write-side shutdown

qio_channel_rdma_shutdown() reads rdmain for both the input and
output contexts.  As a result, a write-side shutdown marks the input
context as errored while leaving the output context active.  A shutdown
of both directions also fails to stop the output context.

Read rdmaout from the output context so each shutdown direction marks
the corresponding RDMA context as errored.

Fixes: 54db882f073a ("migration: implement the shutdown for RDMA QIOChannel")
