Fix for gcell corrrectness/performance problem. Replaces mfc_sync
with appropriate use of tag and fenced get. We could pick up a bit of additional performance by double buffering the the local store job descriptor, but that's left for a rainy day. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@8090 221aa14e-8319-0410-a670-987f0aec2ac5
