block-io: introduce coroutine_fn duplicates for bdrv_common_block_status_above callers
bdrv_common_block_status_above() is a g_c_w, and it is being called by many "wrapper" functions like bdrv_is_allocated(), bdrv_is_allocated_above() and bdrv_block_status_above(). Because we want to eventually split the coroutine from non-coroutine case in g_c_w, create duplicate wrappers that take care of directly calling the same coroutine functions called in the g_c_w.
