rust_binder: Fix build failure if !CONFIG_COMPAT

Browse source 
The bindgen utility cannot handle "#define compat_ptr_ioctl NULL" in the
C header, so we need to handle this case on our own.

Simply skip this field in the initializer when !CONFIG_COMPAT as the
SAFETY comment above this initializer implies this is allowed.
