cxl/hdm: Skip emulation when driver manages mem_enable

Browse source

If the driver is allowed to enable memory operation itself then it can
also turn on HDM decoder support at will.

With this the second call to cxl_setup_hdm_decoder_from_dvsec(), when
an HDM decoder is not committed, is not needed.
