efi/runtime-wrappers: check EFI_RUNTIME_SERVICES before using efi_rts_work

Browse source

Move the EFI_RUNTIME_SERVICES check to the top of __efi_queue_work() and
return directly, so a caller that finds runtime services disabled returns
without touching the shared efi_rts_work. No functional change.

This prepares for bounding the wait, where a timeout will clear
EFI_RUNTIME_SERVICES while the leaked worker still owns efi_rts_work; a
later caller must then bail out before reinitialising it.
