Ok, this one here is a bit more complicated, but for an RFC I've
figured I can be a bit sloppy. So just convert ever mutex_lock call,
including the interruptible one. Since other places (e.g. in the
execbuf ioctl) take the mode_config.mutex without bothering with
interruptible handling, I've figured I should be able to get away with
this in a few more places ...
