[PATCH 21.11] net/softnic: fix maybe-uninitialized warning

[Kevin Traynor]

In pmd_mtr_stats_read() 'struct rte_mtr_stats s' is initialized
during the call to mtr_stats_convert() but on some systems it
is triggering a compiler warning. e.g.

drivers/net/softnic/rte_eth_softnic_meter.c:916:25: error: 's'
   may be used uninitialized [-Werror=maybe-uninitialized]

Initialize the struct in pmd_mtr_stats_read() to avoid warnings.
