KVM: arm64: Fix meta-page unsharing in pKVM hyp tracing
As the hyp_trace_buffer_unshare_hyp() function name suggests we should
unshare all the previously shared pages, otherwise we leak hyp-shared
pages which won't be reusable for hyp memory.
Fix the typo by calling __unshare_page() on the meta-page, ensuring all
previously shared pages are correctly unshared.
