If PXP arb-session is being attempted on older hardware SKUs or
on hardware with older, unsupported, firmware versions, then don't
report the failure with a drm_error. Instead, look specifically for
the API-version error reply and drm_dbg that reply. In this case, the
user-space will eventually get a -ENODEV for the protected context
creation which is the correct behavior and we don't create unnecessary
drm_error's in our dmesg (for what is unsupported platforms).
Changes from prio revs:
v2 : - remove unnecessary newline. (Jani)
v1 : - print incorrect version from input packet, not output.
