cxl/port: Use scoped_guard()/guard() to drop device_lock() for cxl_port

A device_lock() and device_unlock() pair can be replaced by a cleanup
helper scoped_guard() or guard(), that can enhance code readability. In
CXL subsystem, still use device_lock() and device_unlock() pairs for cxl
port resource protection, most of them can be replaced by a
scoped_guard() or a guard() simply.
