pixelstats: Don't log type: action multiple times

LOGBUILDER_TYPE, TYPE_ACTION was being logged with each
integer field.

example current log line:
sysui_multi_action: [757,1424,758,4,758,4,1425,416370725]

the first 758, 4 pair is expected.

The following 758, 4 preceeding 1425, 416370725 was
accidental.  remove the duplicate logging.
