Subject: [PATCH 1/5] dm: move dm_table_destroy() to same header as dm_table_create()

From: Brian Norris <briannorris@...omium.org>

If anyone is going to use dm_table_create(), they probably should be
able to use dm_table_destroy() too. Move the dm_table_destroy()
definition outside the private header, near dm_table_create()
