x86/tsc: Remove the unused check_tsc_disabled()
check_tsc_disabled() was introduced by commit: c73deb6aecda ("perf/x86: Add ability to calculate TSC from perf sample timestamps") The only caller was arch_perf_update_userpage(), which had been refactored by commit: d8b11a0cbd1c ("perf/x86: Clean up cap_user_time* setting") ... so no need keep and export it any more.
