common/rc: use real device name in _sysfs_dev function

_sysfs_dev try to find the major and minor device numbers of
SCRATCH_DEV, by 'stat -c%t $SCRATCH_DEV' and 'stat -c%T
$SCRATCH_DEV'.

But if the SCRATCH_DEV is symlink (e.g: /dev/mapper/
testvg-scratchdev), stat command can't find correct device numbers.
So try to find the real name of the SCRATCH_DEV at first.
