do_blockdev_direct_IO() can call dio_cleanup() before submitting
all bios. This will be inconvenient for us because we need to keep
preallocated structure in sdio which we attach to bio on submit and
it is natural to cleanup unused allocation in dio_cleanup().
Since dio_cleanup() is called again after submitting the last bio it is
enough to just remove the first dio_cleanup() call.
