In the function efi_runtime_services_init(), the if check on
efi_rts_work.efi_rts_id in line 728 uses READ_ONCE(), and the comment
explains that this is to reduce reports from KTSAN.

I propose that the check in line 754 undergoes a similar treatment for
consistency and to potentially reduce sanitizer reports.

Thank you.
