common/common_init: disable ms subsystem log gathering for clients

Browse Source 
The log gathering causes large performance degradation to clients
with high message throughputs. This is hopefully a short-term
workaround until per-message logging can be replaced with an
efficient data recording system for post-incident analysis
use-cases.
