[dpdk-dev] [PATCH] event/opdl: fix sprintf with snprintf

[Pallantla Poornima <pallantlax.poornima@intel.com>]

sprintf function is not secure as it doesn't check the length of string.
More secure function snprintf is used.

Fixes: 3c7f3dcfb0 ("event/opdl: add PMD main body and helper function")
Cc: stable@dpdk.org
