cxl/pci: Remove redundant cxl_pci_find_port() call

Remove the redundant port lookup from cxl_rcrb_get_comp_regs() and use the
dport parameter directly. The caller has already validated the port is
non-NULL before invoking this function, and dport is given as a param.
This is simpler than getting dport in the callee and return the pointer
to the caller what would require more changes.
