btrfs: use btrfs_item_size_nr/btrfs_item_offset_nr everywhere
We have this pattern in a lot of places
item = btrfs_item_nr(slot);
btrfs_item_size(leaf, item);
when we could simply use
btrfs_item_size(leaf, slot);
Fix all callers of btrfs_item_size() and btrfs_item_offset() to use the
_nr variation of the helpers.
