Alex Deucher b4ce08aa03 drm/amdgpu: Fix cond_exec handling in amdgpu_ib_schedule() ...

commit b1defcdc44 upstream.

The EXEC_COUNT field must be > 0.  In the gfx shadow
handling we always emit a cond_exec packet after the gfx_shadow
packet, but the EXEC_COUNT never gets patched.  This leads
to a hang when we try and reset queues on gfx11 APUs.
