[PATCH v4 14/19] blockjob: block_job_get_aio_context is a GS function

[Emanuele Giuseppe Esposito]

Move block_job_get_aio_context under the GS category in blockjob.h,
as it is always called with the BQL held.

This is done also to simplify the coming job->aiocontext protection.

For more infos about the GS API, see include/block/block-global-state.h
