Subject: [PATCH net] qed: fix ILT configuration of SRC block

The code refactoring of ILT configuration was not complete, the old
unused variables were used for the SRC block. That could lead to the memory
corruption by HW when rx filters are configured.
This patch completes that refactoring.

Fixes: 8a52bbab39c9 (qed: Debug feature: ilt and mdump)
