Subject: [PATCH] bnx2x: Fix enabling network interfaces without VFs

Git-commit: 52ce14c134a003fee03d8fc57442c05a55b53715

References: stable-5.14.7

commit 52ce14c134a003fee03d8fc57442c05a55b53715 upstream.

This function is called to enable SR-IOV when available,

not enabling interfaces without VFs was a regression.
