Subject: [PATCH net] bnx2x: Fix to prevent inner-reload
Submit 909d9faae2a44 ("bnx2x: Prevent inner-reload while VFs exist")
contained a bug - MTU change was not prevented by it; Instead, it
`randomally' prevented bnx2x_resume() from running [harmless yet wrong].
This moves the check to its correct spot.
