cxl/port: Reduce number of @dport variables in cxl_port_add_dport()

Browse source

In preparation for refactoring cxl_port_add_dport() to add RAS register
setup, cleanup the number of dport variables with a dport_exists() helper.

Kill the @dport needed to check for duplicates, rename @new_dport to
@dport.
