libata: fix ata_pio_sector for CONFIG_HIGHMEM
Data transfers are not required to be block aligned in memory, so they span two pages. Fix this by splitting the call to >sff_data_xfer into two for that case. This has been broken since the initial libata import before the damn of git, but was uncovered by the legacy ide driver removal. Reported-by:kernel test robot <oliver.sang@intel.com> Signed-off-by:
