dump.f2fs: allow to dump data on mounted device
In generic/38[3456], 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.
So it requires dump.f2fs to list/check enabled features on a mounted
device, let's relieve to allow such operation.
