block: Don't acquire AioContext in hmp_qemu_io()
Commit 15afd94a047 added code to acquire and release the AioContext in
qemuio_command(). This means that the lock is taken twice now in the
call path from hmp_qemu_io(). This causes BDRV_POLL_WHILE() to hang for
any requests issued to nodes in a non-mainloop AioContext.
Dropping the first locking from hmp_qemu_io() fixes the problem.
