[oe-core][PATCH 1/4] initramfs-framework/udev: umount /run/media/XXX

["hongxu" <hongxu.jia@windriver.com>]

In initramfs-framework, udev (initramfs-module-udev) calls hook mount.sh to
mount /run/media/XXX which is used by setup-live (initramfs-module-setup-live).
The setup-live calls install-XXX.sh and use /run/media/XXX to do installation

The side effect is while setup-live is not used, after it switches to rootfs,
and the mounted disk could not be released

Release the mounted disk before switch root and after kill udev
