[dpdk-dev] [PATCH v3 2/9] net/bnxt: fix bumping of L2 filter reference count

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

From: Somnath Kotur <somnath.kotur@broadcom.com>

Now that the L2 filter reference count is bumped up in all cases
including bnxt_alloc_filter() which is issued in init, just move this
ref count bump inside the routine issuing the HWRM cmd so that it is
bumped up only if the cmd is successful.

Fixes: 5c1171c97216 ("net/bnxt: refactor filter/flow")
