[PATCH] ata: libata-transport: fix {dma|pio|xfer}_mode sysfs files

[Sergey Shtylyov <s.shtylyov@omp.ru>]

The {dma|pio|xfer}_mode sysfs files are incorrectly handled by the
ata_bitfield_name_match() macro which leads to reading such kind of
nonsense from them:

$ cat /sys/class/ata_device/dev3.0/pio_mode
XFER_UDMA_7, XFER_UDMA_6, XFER_UDMA_5, XFER_UDMA_4, XFER_MW_DMA_4,
XFER_PIO_6, XFER_PIO_5, XFER_PIO_4, XFER_PIO_3, XFER_PIO_2, XFER_PIO_1,
XFER_PIO_0

Using the correct ata_bitfield_name_search() macro fixes that:

$ cat /sys/class/ata_device/dev3.0/pio_mode
XFER_PIO_4
