Removing ABD Parent Child Reference Before Freeing ABD
Moving the call to zfs_refcount_remove_many() in abd_free() to be called
before any of the ABD free variants are called. This is necessary
because abd_free_gang() adjusts the abd_size for the gang ABD. If the
parent's child references are removed after free'ing the gang ABD the
refcount is not adjusted correctly for the parent's children.

I also removed some stray abd_put() in comments and changed
abd_free_gang_abd() -> abd_free_gang().
