Josef Bacik 06b6ad5e01 btrfs-progs: check: check for invalid free space tree entries
While testing some changes to how we reclaim block groups I started
hitting failures with my TEST_DEV.  This occurred because I had a bug
and failed to properly remove a block groups free space tree entries.
However this wasn't caught in testing when it happened because
btrfs check only checks that the free space cache for the existing block
groups is valid, it doesn't check for free space entries that don't have
a corresponding block group.

Fix this by checking for free space entries that don't have a
corresponding block group.  Additionally add a test image to validate
this fix.
