efi/runtime-wrappers: factor out efi_rts_park_worker()
x86's efi_crash_gracefully_on_page_fault() ends in an infinite
schedule() loop so the kworker that faulted in firmware never runs
efi_rts_wq again. A later change needs the same "park this worker
forever" primitive on the runtime service timeout path, so factor the
loop into a shared efi_rts_park_worker() and call it from the x86
page-fault handler.
No functional change.
