Subject: [PATCH 4.14 73/77] sc16is7xx: move label err_spi to correct section

From: Guoqing Jiang <gqjiang@...e.com>

commit e00164a0f000de893944981f41a568c981aca658 upstream.

err_spi is used when SERIAL_SC16IS7XX_SPI is enabled, so make
the label only available under SERIAL_SC16IS7XX_SPI option.
Otherwise, the below warning appears.

drivers/tty/serial/sc16is7xx.c:1523:1: warning: label ‘err_spi’ defined but not used [-Wunused-label]
 err_spi:
  ^~~~~~~
