e1000: remove unused and incorrect code
The e1000_clear_vfta function was triggering a warning in kbuild-bot
testing. It's actually a bug but has no functional impact.
drivers/net/ethernet/intel/e1000/e1000_hw.c:4415:58: warning: Same expression in both branches of ternary operator. [duplicateExpressionTernary]
Fix this warning by removing the offending code and simplifying
the routine to do exactly what it did before, no functional
change.
