phyp: Fix NULL dereference in phypConnectOpen

Browse Source 
Coverity found out that commit cd490086 caused a possible NULL pointer
dereference.  This is due to the fact, that phyp_driver is NULL at the
time of closing the socket, instead of connection_data, which kept the
socket before the mentioned commit, could not be NULL.

However, internal_socket is still the local socket that can be
closed, even unconditionally, if we initialize it to -1.
