Fixes the case where a PCI device string identifier contains non-ASCII UTF-8.

A particular example is Mellanox Connext-X 5 EN MT27800:

28:00.0 Ethernet controller: Mellanox Technologies MT27800 Family [ConnectX-5]
        Subsystem: Mellanox Technologies ConnectX®-5 EN network interface card, 100GbE single-port QSFP28, PCIe3.0 x16, tall bracket; MCX515A-CCAT

Is similar fix required in line 214 as well?

 name, value = line.decode('utf-8').split("\t", 1)

Apparently yes, though the above patch was enough to fix our usage of dpdk-devbind. 

Same string appears in output of lspci -vmmks. I will update the patch and resubmit. 

Thanks for your help!
