scsi: sd: set max_hw_wzeroes_unmap_sectors if device supports SD_ZERO_*_UNMAP
When the device supports the Write Zeroes command and the zeroing mode
is set to SD_ZERO_WS16_UNMAP or SD_ZERO_WS10_UNMAP, this means that the
device supports unmap Write Zeroes, so set the corresponding
max_hw_write_zeroes_unmap_sectors to max_write_zeroes_sectors on the
device's queue limit.
