migration/savevm.c: reorder usage and assertion of mis->from_src_file

Browse Source 
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: 39675ffffb ("migration: Move the yank unregister of channel_close out")
