libsel4utils: IA32: Squash compiler warnings.

GCC 5.3.1 warns that these variables are used uninitialised. The cause is that
they are provided to an `asm` block as inputs despite not actually being inputs
to the contained `asm`. This commit silences these warnings reducing confusion
in a project build.
