btrfs/14[01]: Use proper helper to get both devid and physical for corruption

Browse Source 
[BUG]
With btrfs-progs v5.4, btrfs/140 and btrfs/141 will fail.

[CAUSE]
Both tests are testing re-silvering of RAID1, thus they need to corrupt
on-disk data.

This requires to do manual logical -> physical bytes mapping in the test
case.
However the test case itself uses too many hard coded helper to grab
physical offset, which will change with mkfs.btrfs.

[FIX]
Use more flex helper, to get both devid and physical for such
corruption.
