[PATCH v3 4/5] block-backend: process zoned requests in the current AioContext

[Stefan Hajnoczi <stefanha@redhat.com>]

Process zoned requests in the current thread's AioContext instead of in
the BlockBackend's AioContext.

There is no need to use the BlockBackend's AioContext thanks to CoMutex
bs->wps->colock, which protects zone metadata.
