RH-Commit: [1/2] 682c1b81b42959d9d91e0f68cd70e9753e53a279
There is only user of bdrv_qiov_is_aligned(), so move the alignment
function to there and make it static.

RH-Commit: [2/2] 0e01d51cfb21ca43283626c2367e5c5d0d531736
An iov length needs to be aligned to the logical block size, which may
be larger than the memory alignment.
