References: jsc#SLE-15368
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/net/ethernet/intel/e1000/e1000_hw.c: In function e1000_phy_init_script:
drivers/net/ethernet/intel/e1000/e1000_hw.c:132:6: warning: variable ‘ret_val’ set but not used [-Wunused-but-set-variable]
`ret_val` is never used, so remove it.
