PM: hibernate: split and simplify hib_submit_io

Split hib_submit_io into a sync and async version.  The sync version is
a small wrapper around bdev_rw_virt which implements all the logic to
add a kernel direct mapping range to a bio and synchronously submits it,
while the async version is slightly simplified using the
bio_add_virt_nofail for adding the single range.
