[PATCH 4.19 252/293] bnx2x: Fix enabling network interfaces without VFs

[Greg Kroah-Hartman]

From: Adrian Bunk <bunk@xxxxxxxxxx>

commit 52ce14c134a003fee03d8fc57442c05a55b53715 upstream.

This function is called to enable SR-IOV when available,
not enabling interfaces without VFs was a regression.
