ocfs2: turn __ocfs2_remove_inode_range() into ocfs2_remove_btree_range()
This patch genericizes the high level handling of extent removal. ocfs2_remove_btree_range() is nearly identical to __ocfs2_remove_inode_range(), except that extent tree operations have been used where necessary. We update ocfs2_remove_inode_range() to use the generic helper. Now extent tree based structures have an easy way to truncate ranges.
