[dpdk-dev] [PATCH] eal: fix device iterator issue to find device for class type

[Vijay Srivastava <vijay.srivastava@xilinx.com>]

devarg parser rte_devargs_layers_parse() does not configures
devargs->bus_str for class type. rte_dev_iterator_init is not
setting devargs->bus_str to NULL before passing it to devarg parser.
It results junk value for bus_str and due to this device
iterator is unable to find device for class type.

Bugzilla ID: 862
Fixes: 9a1a9e4a2ddd (devargs: support path value with global device syntax)
