drm/amdkfd: Extend gfx12 trap handler fix to gfx10/11

In commit fda812eb ("drm/amdkfd: gfx12 context save/restore trap handler fixes")
the following fix was introduced but incorrectly restricted to gfx12.
The same issue and a corresponding fix apply to gfx10 and gfx11.

Do not overwrite TRAPSTS.{SAVECTX,HOST_TRAP} when restoring this
register. Both of these fields can assert while the wavefront is
running the trap handler.
