  Fix fast path array index which is used for passing L2 handles to RSS
indirection table, properly distribute rxq handles for indirection table.
Currently, it is using the local copy of indirection table. When the RX
queue configuration changes the local copy becomes invalid.

Fixes: 69d7ba88f1a1 ("net/qede/base: use L2-handles for RSS configuration")
