[PATCH] drm/amdgpu/userq: Fix unreachable code in amdgpu_runtime_idle_check_userq()

[Srinivasan Shanmugam]

Changed the control flow to use break statements instead of goto to exit
loops when a busy user queue is detected.

Fixes the below:
drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c:2751 amdgpu_runtime_idle_check_userq() warn: ignoring unreachable code.
