Jian J Wang 2a6ede28fd ShellPkg: Fix misuses of AllocateCopyPool
AllocateCopyPool(AllocationSize, *Buffer) will copy "AllocationSize" bytes of
memory from old "Buffer" to new allocated one. If "AllocationSize" is bigger
than size of "Buffer", heap memory overflow occurs during copy.

One solution is to allocate pool first then copy the necessary bytes to new
memory. Another is using ReallocatePool instead if old buffer will be freed
on spot.
