[PATCH 3.16.y-ckt 042/126] snmp: Remove duplicate OUTMCAST stat increment

[Luis Henriques]

3.16.7-ckt22 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Neil Horman <nhorman@xxxxxxxxxxxxx>

commit 41033f029e393a64e81966cbe34d66c6cf8a2e7e upstream.

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
