Recently return value of umad_open_port() was changed from number of umad
device to fd (in order to support multiple opens and for other goodies).
However OpenSM vendor (osm_vendor_ibumad) used this previous undocumented
umad_open_port() return value semantic for resolving number of
/dev/../issm* device (which is needed for PortInfo capmask IsSM bit
setup). So currently it is broken.
This patch introduces new umad_get_issm_path() function for explicit
issm device path resolving which should be used by OpenSM vendor.
