drm/amdgpu: fix ttm_bo calltrace warning in psp_hw_fini

[ Upstream commit 9bb2436be14e3066d88860386c9c74fecd2753d1 ]

The call trace occurs when the amdgpu is removed after
the mode1 reset. During mode1 reset, from suspend to resume,
there is no need to reinitialize the ta firmware buffer
which caused the bo pin_count increase redundantly.
