[PULL 02/14] migration/savevm.c: reorder usage and assertion of mis->from_src_file

From: Sergei Heifetz <[email protected]>

Reorder the code so the assertion of mis->from_src_file occurs before
the call to migration_ioc_unregister_yank_from_file, which dereferences
it in qemu_file_get_ioc.

Fixes: 39675ffffb3394 ("migration: Move the yank unregister of channel_close out")
