block: Convert bdrv_debug_event() to co_wrapper_mixed
bdrv_debug_event() is categorized as an I/O function, and it currently
doesn't run in a coroutine. We should let it take a graph rdlock since
it traverses the block nodes graph, which however is only possible in a
coroutine.
Therefore turn it into a co_wrapper_mixed to move the actual function
into a coroutine where the lock can be taken.
