[PATCH 3/3] btrfs: use helper btrfs_get_block_group

[Anand Jain <anand.jain@oracle.com>]

Use the helper function where it is open coded to increment the
block_group reference count 'bg_count' so that it is less confusing
while reviewing the code. As btrfs_get_block_group() is a one-liner
we could have open-coded it, but its partner function
btrfs_put_block_group() isn't one-liner which does the free part in it.
