drm/amdkfd: allow compute partition mode switch with cgroup exclusions
The KFD currently bars a compute partition mode switch while a KFD
process exists.
Since cgroup excluded devices remain excluded for the lifetime of a KFD
process and user space is able to mode switch single devices, allow
users to mode switch a device with any running process that has been
cgroup excluded from this device.
