ACPICA: dispatcher: Use acpi_ds_clear_operands() in acpi_ds_call_control_method()

When deleting the previous walkstate operand stack
acpi_ds_call_control_method() was deleting obj_desc->Method.param_count
operands. But Method.param_count does not necessarily match
this_walk_state->num_operands, it may be either less or more.

After correcting the for loop to check `i < this_walk_state->num_operands`
the code is identical to acpi_ds_clear_operands(), so just outright
replace the code with acpi_ds_clear_operands() to fix this.
