bcache-tools: Update super block version in bch_set_feature_* routines
When calling bch_set_feature_* routines, it indicates the super block
supports feature set and its version of cache device should at least be
BCACHE_SB_VERSION_CDEV_WITH_FEATURES.
In order to always keep the cache device super block version being
updated, this patch checks whether the super block version is set
correctly when calling bch_set_feature_* routines, if not then set
the version to BCACHE_SB_VERSION_CDEV_WITH_FEATURES.
