pcap_io: introduce init_once helper that is called with priviledges
When using netsniff-ng with dropping priviledges, we have to introduce another pcap helper function that is called once before we drop the priviledges. In this function we have to invoke the disc I/O scheduler policy, because it needs priviledges. Otherwise netsniff-ng will fail with "Failed to set io prio for pid" on startup, since we're not root anymore.

x86/mce: Make timer handling more robust
Erik reported that on a preproduction hardware a CMCI storm triggers the BUG_ON in add_timer_on(). The reason is that the per CPU MCE timer is started by the CMCI logic before the MCE CPU hotplug callback starts the timer with add_timer_on(). So the timer is already queued which triggers the BUG. Using add_timer_on() is pretty pointless in this code because the timer is strictlty per CPU, initialized as pinned and all operations which arm the timer happen on the CPU to which the timer belongs. Simplify the whole machinery by using mod_timer() instead of add_timer_on() which avoids the problem because mod_timer() can handle already queued timers. Use __start_timer() everywhere so the earliest armed expiry time is preserved.
