vc/amd/agesa/[...]/Config: Avoid out-of-bounds warnings
The memNTrainFlowControl array is generating Coverity warnings
in multiple places in code where it attempts to write to index 1.
The array is defined as either 2 elements or 1 of NULL depending
on #if (AGESA_ENTRY_INIT_POST == TRUE). This is likely a false
alarm from Coverity (memory should not be training outside of a
POST), but adding a second NULL element for the
AGESA_ENTRY_INIT_POST == FALSE case. Tested on Lenovo G505s.
