jffs2: free jffs2_sb_info through jffs2_kill_sb()
When an invalid mount option is passed to jffs2, jffs2_parse_options()
will fail and jffs2_sb_info will be freed, but then jffs2_sb_info will
be used (use-after-free) and freeed (double-free) in jffs2_kill_sb().
Fix it by removing the buggy invocation of kfree() when getting invalid
mount options.
