anv: Fix I915_PARAM_HAS_CONTEXT_FREQ_HINT check

Browse source 
When I915_PARAM_HAS_CONTEXT_FREQ_HINT is not supported the
intel_ioctl(fd, DRM_IOCTL_I915_GETPARAM, &gp) will return -1 and that
will cause i915_gem_get_param() to return false.

val will be different than 1 when not using GuC submission, so we are
forcing val check to ensure this holds good in platforms that doesn't
support GuC submission.

Fixes: d52dd5a9 ("anv/drirc: add option to provide low latency hint")
