net: macb: Remove 'unlikely' optimization
Coverage data suggests that the unlikely case of receiving data while
the receive handler is running may not be that unlikely.
Coverage data after running iperf for a while:
91320: 891: work_done = bp->macbgem_ops.mog_rx(bp, budget);
91320: 892: if (work_done < budget) {
2362: 893: napi_complete(napi);
-: 894:
-: 895: /* Packets received while interrupts were disabled */
4724: 896: status = macb_readl(bp, RSR);
2362: 897: if (unlikely(status)) {
762: 898: if (bp->caps & MACB_CAPS_ISR_CLEAR_ON_WRITE)
762: 899: macb_writel(bp, ISR, MACB_BIT(RCOMP));
-: 900: napi_reschedule(napi);
-: 901: } else {
1600: 902: macb_writel(bp, IER, MACB_RX_INT_FLAGS);
-: 903: }
-: 904: }
