Subject: [PATCH] net/bnxt: fix to move a flow to a different queue

[ upstream commit 16fea16455f4c0d23585fc4f00bbbcf1aae6bc73 ]

While moving a flow to a different destination queue,
the l2_filter_id being passed to the FW command was incorrect.
Fix it by re-using the matching filter's l2_filter_id since
that is supposed to be the same in this case.

Fixes: 5ef3b79fdfe6 ("net/bnxt: support flow filter ops")
