base-modem-at: set error if NULL port detected
Users of mm_base_modem_at_command_in_port() can now directly pass the result
of mm_base_modem_peek_port_primary() or mm_base_modem_peek_port_secondary(),
which may be NULL if no such port exists in the modem. So we'll gracefully
detect the NULL port and complete the async operation with an error.
