net/vdev_netvsc: fix automatic probing

The vdev_netvsc driver allows an automatic probe in Hyper-V VM systems
unless it was already specified by the EAL command line.

The detection of a specified NetVSC device is wrongly done by comparing
the vdev_netvsc driver name to all the vdev devices names, including
the suffix device index. Thus, if the user specifies the vdev_netvsc
device by adding an index to the device name, the comparison fails.
Consequently, the vdev_netvsc driver may automatically probe NetVSC
devices, despite the NetVSC device that was specified by the EAL command
line.

Compare the vdev_netvsc driver name to the devices names without the
index.
