libata: fix off-by-one error in ata_tf_read_block()
commit ac8672ea922bde59acf50eaa1eaa1640a6395fd2 upstream.
ata_tf_read_block() has off-by-one error when converting CHS address
to LBA. The bug isn't very visible because ata_tf_read_block() is
used only when generating sense data for a failed RW command and CHS
addressing isn't used too often these days.
This problem was spotted by Atsushi Nemoto.
