vc/amd/agesa: Fix uninitialized scalar variable
AllocParams.Persist is used uninitialized when calling HeapAllocateBuffer. This could lead to unpredictable or unintended results. The f15tn and f16 versions of AmdS3Save.c have already addressed this by initializing AllocParams.Persist=0 in the same location in the code, so adding to f14 only.
