Avoid race between ueventloop and uevqloop

ueventloop sets up uevq_lockp and uev_condp, which uevqloop uses.
If uevqloop accesses these structures before ueventloop has
initialized them, it will not wake up to process uevents. This patch
statically initializes these structures so they will always be
initialized. Also, since calling LIST_HEAD(uevq) initializes it,
there is no reason to call INIT_LIST_HEAD on it later.
