[PATCH] drm/amdkfd: fix build failure without CONFIG_DYNAMIC_DEBUG

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

When CONFIG_DYNAMIC_DEBUG is disabled altogether, calling
_dynamic_func_call_no_desc() does not work:

drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_svm.c: In function 'svm_range_set_attr':
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_svm.c:52:9: error: implicit declaration of function '_dynamic_func_call_no_desc' [-Werror=implicit-function-declaration]
   52 |         _dynamic_func_call_no_desc("svm_range_dump", svm_range_debug_dump, svms)
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_svm.c:3564:9: note: in expansion of macro 'dynamic_svm_range_dump'
 3564 |         dynamic_svm_range_dump(svms);
      |         ^~~~~~~~~~~~~~~~~~~~~~

Add a compile-time conditional in addition to the runtime check.

Fixes: 8923137dbe4b2 ("drm/amdkfd: avoid svm dump when dynamic debug disabled")
