[dpdk-dev] [PATCH 4/6] net/bnxt: fix a potential segfault in xstats get

[Somnath Kotur]

From: Ajit Khaparde <ajit.khaparde at broadcom.com>

We would hit a segfault in bnxt_dev_xstats_get_op() if xstats
argument is NULL, Check if the argument is NULL and return appropriately.

Fixes: bfb9c2260be2 ("net/bnxt: support xstats get/reset")
