Fixed rendering bug for source alpha == 0 in OVER fastpath functions

Handling of the case when source alpha is zero was keeping destination
pixel unmodified. But this is different from how generic path behaves.
For example fbOver(0x00200483, 0x9CAC7E9F) == 0x9CCC82FF and the
destination pixel changes from 0x9CAC7E9F to 0x9CCC82FF in spite
of having zero alpha.
