[v2,0/3] drm/panthor: Fix group state reporting

Hello,

What initially started as a simple fix to avoid queueing jobs to a group
that can't be scheduled has turned into a series of three patches
improving the group state reporting. Two of them are actual fixes, the
last one is an improvement to properly report innocence/guiltiness of
a group when a group becomes unusable. With this new
GROUP_STATE_INNOCENT, we can distinguish between
GL_INNOCENT_CONTEXT_RESET and GL_GUILT_CONTEXT_RESET (see this mesa
MR for more details [1]).

Regards,

Boris
