btrfs-progs: mkfs: Enhance minimal device size calculation to fix mkfs failure on small file
Since commit c11e36a29e84 ("Btrfs-progs: Do not force mixed block group
creation unless '-M' option is specified"), mkfs no longer use mixed
block group unless specified manually.
This breaks the minimal device size calculation, which only considered
mixed block group use case.
This patch enhances minimal device size calculation for mkfs, by using
different minimal stripe length (calculated from code) for different
profiles, and use them to calculate minimal device size.
