ada: Fix spurious error on generic state in SPARK
The public state of a generic package needs not be part of the state of
the enclosing unit, only the state of instantiations need to be accounted
for in the enclosing package. Now fixed.
gcc/ada/
* sem_util.adb (Find_Placement_In_State_Space): Stop search for
placement when reaching the public state of a generic package.
