Add support for operation code 3 (OC3) of the
Perform-Network-Subchannel-Operations (PNSO) function
of the Channel-Subsystem-Call (CHSC) instruction.

PNSO provides 2 operation codes:
OC0 - BRIDGE_INFO
OC3 - ADDR_INFO (new)

Extend the function calls to *pnso* to pass the OC and
add new response code 0108.

Support for OC3 is indicated by a flag in the css_general_characteristics.
