treewide: Replace more open-coded allocation size multiplications
As done treewide earlier, this catches several more open-coded
allocation size calculations that were added to the kernel during the
merge window. This performs the following mechanical transformations
using Coccinelle:
kvmalloc(a * b, ...) -> kvmalloc_array(a, b, ...)
kvzalloc(a * b, ...) -> kvcalloc(a, b, ...)
devm_kzalloc(..., a * b, ...) -> devm_kcalloc(..., a, b, ...)
