Subject: igc: Remove set but not used variables 'ctrl_ext, link_mode'
Patch-mainline: v5.0-rc1
Git-commit: dda458d28567d0bb99ad67180a72aaff2e0adc3b
References: bsc#1118657 FATE#325278

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")
