btrfs: remove use btrfs_remove_free_space_cache instead of variant

Browse Source 
We are calling __btrfs_remove_free_space_cache everywhere to cleanup the
block group free space, however we can just use
btrfs_remove_free_space_cache and pass in the block group in all of
these places.  Then we can remove __btrfs_remove_free_space_cache and
rename __btrfs_remove_free_space_cache_locked to
__btrfs_remove_free_space_cache.
