We've done similar changes before

23f60ef304d6 ("generic/38[3-6]: require project quota to be enabled on
SCRATCH_DEV")

but later it was reverted by

f722c48d4cd5 ("Revert "generic/38[3-6]: require project quota to be
enabled on SCRATCH_DEV"")

Because we use quotactl(2) to check if prjquota is enabled on the given
device (src/feature -P $dev in _require_prjquota), and quotactl(2)
requires the given device is a mounted device.

Thanks,
Eryu
