[PATCH 4.9 69/91] bnx2x: Fix logic to get total no. of PFs per engine

From: Greg Kroah-Hartman

[ Upstream commit ee699f89bdbaa19c399804504241b5c531b48888 ]

Driver doesn't calculate total number of PFs configured on a
given engine correctly which messed up resources in the PFs
loaded on that engine, leading driver to exceed configuration
of resources (like vlan filters etc.) beyond the limit per
engine, which ended up with asserts from the firmware.
