net/igb: fix add/delete of flex filters

Browse Source 
Before this patch, flex_filter->index was always zero when it was read
and used after rte_zmalloc. The corresponding code was therefore moved
into the add and delete parts of the if/else statement.

Fixes: 231d43909a31 ("igb: migrate flex filter to new API")
