btrfs: remove pointless qgroup assignment in block_rsv_release_bytes()

Browse Source 
If num_bytes == (u64)-1, there's no point to set qgroup_to_release to
block_rsv->qgroup_rsv_size as later on we will overwrite that value
without ever reading the variable before that. So simplify things and
remove that assignment.
