ubi-utils: ubinize: add support for skipping CRC check of a static volume when opening
Let's let the user configure static UBI volume with CRC checking at
opening disabled if desired.
Introduce the skip-check setting for vol_flags configuration of a
volume.
There is no point in having both autoresize and skip-check set as
skip-check is reserved for static volumes only and it's useless to have
a static volume's size set to autoresize.
