Currently the AMDGPU_CTX_PRIORITY_* defines are used in both
drm_amdgpu_ctx_in::priority and drm_amdgpu_sched_in::priority.
Extend the comment to mention the CAP_SYS_NICE or DRM_MASTER requirement
is only applicable with the former.

Mildly curious: why didn't one extend ctx_amdgpu_ctx instead of adding
drm_amdgpu_sched? New flag + _u32 fd at the end (for the former) would
have been enough (and tweaking the ioctl permission thingy).
Speaking of flags, drm_amdgpu_sched_in lost its so extending it will
be "fun"
