Some operations cannot be performed during the firmware flashing
process and will be vetoed later in the patchset.
For example, flashing firmware on a device which is already in a flashing
process should be forbidden.

In order to veto those scenarios, add a flag in 'struct net_device' that
indicates when a firmware flash is taking place on the module.
