description:
Add support for SCSI MMC feature 0x0024: hardware assisted defect
management to be passed in mmc_discinfo's device capabilities.

When a device reports support for this the hardware will automatically
remap sectors on read- or write-errors. CD-MRW, DVD+MRW, DVD-RAM and BR-RE
support these.
