btrfs-progs: check: only warn if clearing v1 cache and v2 found 

There are cases where v1 free space cache is still left while user has
already enabled v2 cache.  In that case, we still want to force v1 space
cache cleanup in btrfs-check.

This patch will only warn and not exit if v2 is detected while the user
asked to clear v1.
