The IMA arch code attempts to inspect the "SetupMode" EFI variable by populating a variable called efi_SetupMode_name with the string "SecureBoot" and passing that to the EFI GetVariable service, which obviously does not yield the expected result. Given that the string is only referenced a single time, let's get rid of the intermediate variable, and pass the correct string as an immediate argument. While at it, do the same for "SecureBoot".
