igc: Remove set but not used variable 'pci_using_dac' 

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/ethernet/intel/igc/igc_main.c: In function 'igc_probe':
drivers/net/ethernet/intel/igc/igc_main.c:3535:11: warning:
 variable 'pci_using_dac' set but not used [-Wunused-but-set-variable]

It never used since introduction in commit
d89f88419f ("igc: Add skeletal frame for Intel(R) 2.5G Ethernet Controller support")
