[PATCH 5.18 648/879] gpio: sim: Use correct order for the parameters of devm_kcalloc()

[ Upstream commit c680c6a814a2269427fad9ac417ab16756bceae9 ]

We should have 'n', then 'size', not the opposite.
This is harmless because the 2 values are just multiplied, but having
the correct order silence a (unpublished yet) smatch warning.
