Mangala V e9124ffca7 BUGFIX: Updated ZGEMM microkernel to handle alpha = 0 case ...

BUG:
When alpha real and imaginary is zero
Output is computed as C= Beta * C + A * B instead of C = Beta * C

FIX:
Updated kernel to scale A * B product with alpha in case of alpha=0

Existing framework design:
- When alpha real and imaginary value is zero, framework handles to skip
kernel call to avoid alpha * A * B operation
- SCALM is invoked to perform Beta * C

- Accuracy issue was not observed as alpha=0 was handled in framework
- If we call kernel directly with alpha=0, results would be wrong
- Issue was figured out during microkernel testing using gtestsuite
