drm/amdgpu/gfx9.4.3: skip PTL disable during GPU reset

Browse source

During RAS UE-triggered GPU reset, gfx_v9_4_3_hw_fini() attempts to
send a PTL disable command to PSP. Since PSP is unresponsive at that
point, this produces spurious error logs on all hive nodes:
  PTL command 0xa0000001 failed, PSP response status: 0xFFFFFFFF
  PTL initialization failed (-5)
Skip the PTL disable command when GPU reset is in progress, as PTL
will be properly re-initialized during post-reset recovery via
gfx_v9_4_3_late_init().
