mtip32xx: Remove unwanted code from taskfile error handler
commit e35b94738a2f7caa12017f69ef385cb6b8028965 upstream.
Remove setting and clearing MTIP_PF_EH_ACTIVE_BIT flag in
mtip_handle_tfe() as they are redundant. Also avoid waking
up service thread from mtip_handle_tfe() because it is
already woken up in case of taskfile error.
