libata: Avoid overflow in ata_tf_read_block() when tf->hba_lbal > 127
Phillip O'Donnell <phillip.odonnell@gmail.com> pointed out that the same
sign extension bug that was fixed in commit ba14a9c2 ("libata: Avoid
overflow in ata_tf_to_lba48() when tf->hba_lbal > 127") also appears to
exist in ata_tf_read_block(). Fix this by adding a cast to u64.
