libata: add ATA_HORKAGE_MAX_SEC_1024 to revert back to previous max_sectors limit
commit af34d637637eabaf49406eb35c948cd51ba262a6 upstream.
Since no longer limiting max_sectors to BLK_DEF_MAX_SECTORS (commit 34b48db66e08),
data corruption may occur on ST380013AS drive configured on 82801JI (ICH10 Family)
SATA controller. This patch will allow the driver to limit max_sectors as before
# cat /sys/block/sdb/queue/max_sectors_kb
512
I was able to double the max_sectors_kb value up to 16384 on linux-4.2.0-rc2
before seeing corruption, but seems safer to use previous limit. Without this
patch max_sectors_kb will be 32767.
tj: Minor comment update.
