Fix uninitialized read in MGAEnableSecondOutPut
`MGAGRestore` allocated `ModeInfo` without initializing its memory and then
passes it into `MGAEnableSecondOutPut` via `MGAEnableSecondOutPut(pScrn, &ModeInfo);`.
`MGAEnableSecondOutPut` then reads the unitialized memory in the line
`if ( !(pModeInfo->flSignalMode & POS_HSYNC) )`.
This patch just zeroes the memory to prevent those branches to be randomly
taken.
