[PATCH net] ionic: move filter sync_needed bit set

[PATCH net] ionic: move filter sync_needed bit set

[Shannon Nelson]

Move the setting of the filter-sync-needed bit to the error
case in the filter add routine to be sure we're checking the
live filter status rather than a copy of the pre-sync status.

Fixes: 969f84394604 ("ionic: sync the filters in the work task")
