Subject: [PATCH] drm/amdkfd/kfd_mqd_manager_v10: Fix missing break in switch
 statement

Add missing break statement in order to prevent the code from falling
through to case KFD_MQD_TYPE_COMPUTE.

This bug was found thanks to the ongoing efforts to enable
-Wimplicit-fallthrough.

Fixes: 14328aa58ce5 ("drm/amdkfd: Add navi10 support to amdkfd. (v3)")
Cc: stable@...r.kernel.org
