[stable:PATCH v5.10.105] arm64: kvm: Fix copy-and-paste error in bhb templates for v5.10 stable

[James Morse <james.morse@arm.com>]

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.
