cxl/hdm: Skip emulation when driver manages mem_enable
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.
Fixes: b777e9bec960 ("cxl/hdm: Emulate HDM decoder from DVSEC range registers")
