block: use bdrv_co_debug_event in coroutine context 

bdrv_co_debug_event was recently introduced, with bdrv_debug_event
becoming a wrapper for use in unknown context.  Because most of the
time bdrv_debug_event is used on a BdrvChild via the wrapper macro
BLKDBG_EVENT, introduce a similar macro BLKDBG_CO_EVENT that calls
bdrv_co_debug_event, and switch whenever possible.
