mmc: queue: bring discard_granularity/alignment into line with SCSI
SCSI defines discard alignment as the offset to the first
optimal discard. In the case of SD/MMC, that is always zero
which is the default.
SCSI defines discard granularity as a hint of a optimal
discard size. That is much better expressed by the MMC
"preferred erase size" (pref_erase) field.
