stlink: always use a valid endpoint
In order to extend the driver to support stlink-server over TCP,
we should always use a valid endpoint, as stlink-server is not permissive
and do not accept the invalid STLINK_NULL_EP.
STLINK_NULL_EP value was used for commands without an expected reply,
this value could be replaced with a valid endpoint without any impact
when the size is set to zero.
