kobj: Use M_WAITOK in kobj_init

Blocking allocation is safe in all of the current callers of kobj_init
(most of them do a M_WAITOK malloc of the structure passed as the
first argument to kobj_init just before calling it).  kobj_init
doesn't return an error code but instead panics if the nested malloc
in kobj_class_compile1 fails, so using M_WAITOK here is more robust.
