x86/tdx: Drop exported function tdx_quirk_reset_page()

Browse source

KVM invokes tdx_quirk_reset_page() to reset TDX control pages (including
S-EPT pages, TDR page, etc.), as all those pages are allocated by KVM TDX
and thus always have struct page.

However, it's also reasonable for KVM to reset those TDX control pages via
tdx_quirk_reset_paddr() directly, eliminating the need to export two
parallel APIs. Keeping tdx_quirk_reset_page() as a one-line helper in the
header file is also unnecessary.

No functional change intended.
