[PATCH v2 5/7] spice-ppc: avoid casts to lessers types!

[Erlon Cruz <erlon.cruz@xxxxxxxxxxxxxxxxxx>]

From: Fabiano Fidêncio <fabiano@xxxxxxxxxxxx>

    It's breaking PPC's keyboard functionality, once this cast is
    getting the first byte (from left to right) on any architecture,
    what's wrong when we think in a PPC (we should get the last one,
    instead).
