[OE-core] [PATCH] initramfs-framework/udev: call settle before kill

When mount command is executed in rootfs module of initrd, eudev creates
a loop0 device node, applies rules and adds a inotify watch to it. Right
after this step, we execute finish which first tries to kill any running
udevd daemon before doing a switch_root.
In some cases, it is possible that switch_root is executed before
inotify_add_watch was actually processed which would lead to errors like:
| inotify_add_watch(6, /dev/loop0, 10) failed: No such file or directory
Make sure that we process all the events in queue before actually trying
to kill udevd to prevent this race.
Fixes [YOCTO #12861]
