Subject: snmp: Remove duplicate OUTMCAST stat increment
From: Neil Horman <nhorman@tuxdriver.com>
[ Upstream commit 41033f029e393a64e81966cbe34d66c6cf8a2e7e ]
the OUTMCAST stat is double incremented, getting bumped once in the mcast code
itself, and again in the common ip output path. Remove the mcast bump, as its
not needed
Validated by the reporter, with good results
