[PATCH v2 i-g-t] demos/intel_sprite_on: Fix connector iteration bug

[Jim Bride <jim.bride@linux.intel.com>]

Instead of looping until the first disconnected port is found,
now go through all possible connectors, drawing the sprite on
any connected display.

v2: Print a message if we don't find any valid connectors.
