[PATCH 1/5] drm/i915/guc: Don't turn on ctb_recv.is_in_error flag

[Michal Wajdeczko]

CTB descriptor flag "is_in_error" is used by the GuC to indicate that
it has stopped processing messages on H2G CT buffer due to some earlier
failures (like bad head/tail offsets in descriptor).

This flag is ignored by the GuC on G2H CT buffer (which is our RECV).

We can also skip error about corrupted message since we already have
similar error in other function.
