XFA: merge patch from CL 727083002, zero local variables.

Zero initialize ch to avoid possible bug - conditions are very subtle.

Whether ch and iRet are read without being initialized depends on complex
preconditions and cannot be determined by looking at these function.
Therefore it seems prudent to zero initialize them to avoid any risk.
