[dpdk-dev] [PATCH] librte_pmd_bond: remove memory alloc for rte_pci_driver

[dpdk-dev] [PATCH] librte_pmd_bond: remove memory alloc for rte_pci_driver

[Jia Yu]

eth_driver already contains rte_pci_driver data structure.
Allocating rte_pci_driver without referencing it after bond
creation causes memory leakage.

Hey Thomas, I've been away for a few days but this looks fine, I'll ack
