Subject: IB/core: Change filter function return type from int to bool
Patch-mainline: v4.19-rc1
Git-commit: dd81b2c8a3339c813568d07091fcd0d97dd0cf41
References: bsc#1103992 FATE#326009
Filter functions returns either 0 or 1, therefore better change their
return type from int to bool to reflect the same. Additionally some
filter functions have suffix of _filter some doesn't. Make all filter
function consistent to have __filter suffix to improve code readability.
