[PATCH] drm/amdgpu: save the funcs of gfx software rings

[Trigger.Huang at amd.com]

From: Trigger Huang <Trigger.Huang at amd.com>

Currently the funcs variable of a gfx software ring is not set. So
if it is visited somewhere, it will lead to error logic being
executed. For example, if we want to call some callbacks in funcs of
a gfx software ring, like per ring reset, it will be failed due to
funcs is NULL.
