drm/amdkfd/kfd_mqd_manager_v10: Avoid fall-through warning

In preparation to enabling -Wimplicit-fallthrough, this patch silences
the following warning:

drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_mqd_manager_v10.c: In function ‘mqd_manager_init_v10’:
./include/linux/dynamic_debug.h:122:52: warning: this statement may fall through [-Wimplicit-fallthrough=]
 #define __dynamic_func_call(id, fmt, func, ...) do { \
                                                    ^
./include/linux/dynamic_debug.h:143:2: note: in expansion of macro ‘__dynamic_func_call’
  __dynamic_func_call(__UNIQUE_ID(ddebug), fmt, func, ##__VA_ARGS__)
  ^~~~~~~~~~~~~~~~~~~

   ^~~~~~~~

  case KFD_MQD_TYPE_COMPUTE:

by removing the call to pr_debug() in KFD_MQD_TYPE_CP:

"The mqd init for CP and COMPUTE will have the same  routine." [1]

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