btrfs: change BUG_ON to assertion in reset_balance_state()

Browse Source 
The balance state machine is complex so it's good to verify the
assumptions in helpers, however reset_balance_state() is used
at the end of balance and fs_info::balance_ctl is properly set up before
and protected by the exclusive op ownership in btrfs_balance().
