btrfs: return block group directly at btrfs_next_block_group()

At btrfs_next_block_group(), we have this long line with two statements:

  cache = btrfs_lookup_first_block_group(...); return cache;

This makes it a bit harder to read due to two statements on the same
line, so change that to directly return the result of the call to
btrfs_lookup_first_block_group().
