Subject: ice: Remove likely for napi_complete_done
Patch-mainline: v5.18-rc1
Git-commit: a4e186693cbe43b88ec577be9859276c42d16b3f
References: jsc#PED-376
Remove the likely before napi_complete_done as this is the unlikely case
when busy-poll is used. Removing this has a positive performance impact
for busy-poll and no negative impact to the regular case.
