btrfs: ref-verify: free ref cache before clearing mount opt
As clearing REF_VERIFY mount option indicates there were some errors in a
ref-verify process, a ref cache is not relevant anymore and should be
freed.
btrfs_free_ref_cache() requires REF_VERIFY option being set so call
it just before clearing the mount option.
