Paolo Bonzini 8238010b26 block: make discard asynchronous

This is easy with the thread pool, because we can use s->is_xfs and
s->has_discard from the worker function.

QEMU has a widespread assumption that each I/O operation writes less
than 2^32 bytes.  This patch doesn't fix it throughout of course,
but it starts correcting struct RawPosixAIOData so that there is
no regression with respect to the synchronous discard implementation.
