[PATCH 09/17] btrfs: move btrfs_chunk_item_size out of ctree.h

[Josef Bacik <josef@toxicpanda.com>]

This is more of a volumes related helper, additionally it has a BUG_ON()
which isn't defined in the related header.  Move the code to volumes.c,
change the BUG_ON() to an ASSERT(), and move the prototype to volumes.h.
