  [AMDGPU] Fix PromoteAlloca size check of alloca for store (#72528)

When storing a subvector, too many element were written when the
size of the alloca is smaller than the size of the vector store.
This patch checks for the minimum of the alloca vector and the
store vector to determine the number of elements to store.
