btrfs: rename btrfs_create_block_group_cache to btrfs_create_block_group

'struct btrfs_block_group' used to be called 'struct
btrfs_block_group_cache' but got renamed to btrfs_block_group with
commit 32da538 ("btrfs: rename btrfs_block_group_cache").

Rename btrfs_create_block_group_cache() to btrfs_create_block_group() to
reflect that change.
