x86/ioremap: Fix CONFIG_EFI=n build
commit 870b4333a62e45b0b2000d14b301b7b8b8cad9da upstream.
In order to use efi_mem_type(), one needs CONFIG_EFI enabled. Otherwise
that function is undefined. Use IS_ENABLED() to check and avoid the
ifdeffery as the compiler optimizes away the following unreachable code
then.
Fixes: 985e537a4082 ("x86/ioremap: Map EFI runtime services data as encrypted for SEV")
