  [NVPTX] Fix vaarg store alignment (#127067)

There is an issue with different alignment applied to store and load of
vaargs in NVPTX backend.
Current `CodeGen/NVPTX/vaargs.ll` demonstrates this discrepancy. Store
occurs with offsets `0,4,12,20`, but load with `0,8,16,24`.

This patch attempts to unify the alignment approach for callee and
caller.
