ixgbe: Fix possible null-dereference in error path

Browse source

commit 508a8c9e26 upstream.

In ixgbe_probe, the code at label err_dma can dereference adapter
when it has a NULL value. The check is there to avoid disabling a
disabled device. When adapter is NULL, treat it as if the device
is enabled, because it is enabled in that case.
