Emanuele Giuseppe Esposito 82618d7bc3 block: Convert bdrv_get_allocated_file_size() to co_wrapper ...

bdrv_get_allocated_file_size() 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 to move the actual function into a
coroutine where the lock can be taken.
