Joseph Greathouse 04ead59f0b Fix errors in occupancy calculation function (#1926) ...

Fix two errors in hipOccupancyMaxActiveBlocksPerMultiprocessor.
1) Fix a possible segfault if the user passed in a null pointer for
   the numBlocks value.
2) Handle the situation when the user is asking for a block size
   that is larger than what the target device can hold within a
   single block.
