btrfs-progs: fix space_cache generation again when free-space-tree is enabled

Browse source 
In commit a138daac17 ("btrfs-progs: mkfs: set super_cache_generation
to 0 if we're using free space tree") the space cache (v1) generation
was reset to 0 to let kernel know it's not used when the free-space-tree
is enabled.

This got broken again in 5.14 when the free space tree code got
refactored in 4b6cf2a3eb ("btrfs-progs: mkfs: generate free space tree
at make_btrfs() time").

Reset the space cache generation to 0.
