can: peak_pci: prevent use after free at netdev removal
commit 0b5a958cf4df3a5cd578b861471e62138f55c85e upstream.
As remarked by Christopher R. Baker in his post at
http://marc.info/?l=linux-can&m=139707295706465&w=2
there's a possibility for an use after free condition at device removal.
This simplified patch introduces an additional variable to prevent the issue.
Thanks for catching this.
