igb: Fix potential invalid memory access in igb_init_module()

Browse source

[ Upstream commit 0566f83d20 ]

The pci_register_driver() can fail and when this happened, the dca_notifier
needs to be unregistered, otherwise the dca_notifier can be called when
igb fails to install, resulting to invalid memory access.
