KVM's infrastructure for spectre mitigations in the vectors in v5.10 and
earlier is different, it uses templates which are used to build a set of
vectors at runtime.

There are two copy-and-paste errors in the templates: __spectre_bhb_loop_k24
should loop 24 times and __spectre_bhb_loop_k32 32.

Fix these.
