block-backend: process zoned requests in the current AioContext

Browse source 
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.
