There's no user of ata_using_mwdma since introduced by commit
b15b3ebae ("libata: Fix a large collection of DMA mode mismatches")
in 2008, so remove it.

This patch makes ata_using_udma return bool due to this
particular function only using either one or zero as its return
value.
This patch also makes ata_using_udma return directly by removing
if condition.
No functional change.
