[PATCH -next] ixgbe: Fix non static symbol warnings

[Wei Yongjun]

From: Wei Yongjun <weiyongj...@huawei.com>

Fixes the following sparse warnings:

drivers/net/ethernet/intel/ixgbe/ixgbe_x550.c:2128:5: warning:
 symbol 'ixgbe_led_on_t_x550em' was not declared. Should it be static?
drivers/net/ethernet/intel/ixgbe/ixgbe_x550.c:2150:5: warning:
 symbol 'ixgbe_led_off_t_x550em' was not declared. Should it be static?
