Fixes gcc '-Wunused-but-set-variable' warning:
drivers/net/ethernet/intel/igc/igc_base.c: In function 'igc_init_phy_params_base':
drivers/net/ethernet/intel/igc/igc_base.c:240:6: warning:
variable 'ctrl_ext' set but not used [-Wunused-but-set-variable]
u32 ctrl_ext;
drivers/net/ethernet/intel/igc/igc_base.c: In function 'igc_get_invariants_base':
drivers/net/ethernet/intel/igc/igc_base.c:290:6: warning:
variable 'link_mode' set but not used [-Wunused-but-set-variable]
u32 link_mode = 0;
It never used since introduction in
commit c0071c7aa5fe ("igc: Add HW initialization code")

I'm not sure that reading IGC_CTRL_EXT is necessary.
