[Qemu-block] [PATCH] block/qed: add missed coroutine_fn markers

[Vladimir Sementsov-Ogievskiy]

qed_read_table and qed_write_table use coroutine-only interfaces but
are not marked coroutine_fn. Happily, they are called only from
coroutine context, so we only need to add missed markers.

Hi!

This is a follow-up for my "block: buffer-based io" series, proposed by
Kevin, based on Kevin's block branch.

Based-on: git://repo.or.cz/qemu/kevin.git block
