Filipe Manana aadb164bdd btrfs: update documentation for a block group's bg_list member 
Currently we are only documenting two uses of the bg_list member of a
block group, but there two more:

1) To track deleted block groups for discard purposes, introduced in
   commit e33e17ee10 ("btrfs: add missing discards when unpinning
   extents with -o discard");

2) To track block groups for automatic reclaim, introduced more recently
   by commit 18bb8bbf13 ("btrfs: zoned: automatically reclaim zones")

So document those two other use cases.
