Move scalar arg processing in btf_prepare_func_args() after all pointer
arg processing is done. This makes it easier to do validation. One
example of unintended behavior right now is ability to specify
__arg_nonnull for integer/enum arguments. This patch fixes this.

voltage_parameters is a point to a struct of type
SET_VOLTAGE_PARAMETERS_V1_3. Passing just voltage_parameters would
not print the right size of the struct variable. So we need to pass
*voltage_parameters to sizeof().
