[rawhide ]overrides: remove kernel pin

The kernel was pinned as the kernel upgrade from
kernel-6.12.0-0.rc7.59.fc42 →> 6.13.0-0.rc0.20241119git158f238aa69d.2.fc42
was causing the multipath.partition kola test to fail.
Now the multipath.partition test is added to the kola-denylist and we
are unpinning the kernel to monitor the working of
kernel-6.13.0-0.rc0.20241119git158f238aa69d.2.fc42
