Subject: [PATCH] mkfs: use geometry generation / helper functions
Git-commit: ebc2e79841949c838d994235727a72e4de854be6
Patch-mainline: v4.17.0-rc1
References: bsc#1129859

Since libxfs now has a function to fill out the geometry structure
and libfrog has a function to pretty-print the geometry, have mkfs
use the two helpers instead of open-coding it.
