Subject: examples/vdpa: remove useless device count
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=fbe6be6ea04cad614a4d2914be2f6da788bcf706

examples/vdpa: remove useless device count

The VDPA example now uses the vDPA class iterator, so
knowing the number of available devices beforehand is
no longer needed.
