[Qemu-devel] [PATCH v4 7/9] dump: Add API to free memory used by creating header, bitmap and page

[qiaonuohan@cn.fujitsu.com]

From: Qiao Nuohan <qiaonuohan@cn.fujitsu.com>

When calling create_header, create_dump_bitmap and create_pages, some memory
spaces are allocated. The following patch will use this function to free these
memory.
