If the arguments are mapped, but are actually not used in the target
region, the compiler still adds attribute TGT_OMP_TARGET_PARAM for such
arguments. It makes the libomptarget to add such parameters to the list
of arguments, passed to the kernel at the runtime, and may lead to
incorrect results/crashes during execution.
