Yes, I think it makes sense to skip touching the BGRT on kexec boot.

As a side note, we should really look at using one of the efi_enabled()
bits to signal when we're booting a kexec'd kernel because it is not at
all obvious that 'efi_setup != 0' means we're in kexec kernel.

But that wants to be a separate patch from this issue.
