There was a segment fault when dump flows with device argument of
dv_flow_en=0. In such case, Verbs flow engine was enabled and fdb
resources were not initialized. It's suggested to use mlx_fs_dump
for Verbs flow dump.
This patch adds verbs engine check, prints warning message and return
gracefully.
