Subject: Remove unnecessary dqcoeff memset.
X-Git-Tag: v1.4.0~374^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=3c7a06c3cce396deecad5a925258f6cf10bcc7ee;p=libvpx

Remove unnecessary dqcoeff memset.

dqcoeff is set to be 0 on initialization. And set back to 0 after being
used everytime.
