Unconditionally unregister yank function in multifd_load_cleanup().
If it is not unregistered here, it will leak and cause a crash
in yank_unregister_instance(). Now if the ioc is still in use
afterwards, it will only lead to qemu not being able to recover
from a hang related to that ioc.
After checking the code, i am pretty sure that ref is always 1
when arriving here. So all this currently does is remove the
unneeded check.
