igb: Remove incorrect "unexpected SYS WRAP" log message
TSAUXC.DisableSystime is never set, so SYSTIM runs into a SYS WRAP every 1100 secs on 80580/i350/i354 (40 bit SYSTIM) and every 35000 secs on 80576 (45 bit SYSTIM). This wrap event sets the TSICR.SysWrap bit unconditionally. However, checking TSIM at interrupt time shows that this event does not actually cause the interrupt. Rather, it's just bycatch while the actual interrupt is caused by, for instance, TSICR.TXTS. The conclusion is that the SYS WRAP is actually expected, so the "unexpected SYS WRAP" message is entirely bogus and just helps to confuse users. Drop it.
