Revert "drivers/net/ethernet/neterion/vxge: Fix a use-after-free bug in vxge-main.c"

This reverts commit 1285de8a0dbe0fb0940c8281f7bc08db78b6d161.

BAR0 is the main (only?) register bank for this device. We most
obviously can't unmap it before the netdev is unregistered.
This was pointed out in review but the patch got reposted and
merged, anyway.

The author of the patch was only testing it with a QEMU model,
which I presume does not emulate enough for the netdev to be brought
up (author's replies are not visible in lore because they kept sending
their emails in HTML).
