m/n/c/devmgr: increase buffer size

The default kernel buffer size for the kobject connection results in
frequent overruns while enumerating devices causing devmgr to restart
and reenumerate. This causes log noise and slower boots, so fix this by
adding an upstream patch to allow setting the buffer size and doing so.
