Subject: ice: Separate if conditions for ice_set_features()
Patch-mainline: v5.2-rc1
Git-commit: 8f529ff912073f778e3cd74e87fb69a36499fc2f
References: jsc#SLE-4803
Set features can have multiple features turned on|off in a single
call. Grouping these all in an if/else means after one condition
is met, other conditions/features will not be evaluated. Break
the if/else statements by feature to ensure all features will be
handled properly.
