acpi/nfit: fix cmd_rc for acpi_nfit_ctl to always return a value



cmd_rc is passed in by reference to the acpi_nfit_ctl() function and the
caller expects a value returned. However, when the package is pass through
via the ND_CMD_CALL command, cmd_rc is not touched. Make sure cmd_rc is
always set.
