[PATCH v3 07/11] block: Convert bdrv_query_image_info to coroutine

[Fabiano Rosas]

This function is a caller of bdrv_do_query_node_info(), which have
been converted to a coroutine. Convert this function as well so we're
closer from having the whole qmp_query_block as a single coroutine.

Also remove the wrapper for bdrv_co_do_query_node_info() now that all
its callers are converted.
