btrfs-progs: check: check symlinks with append/immutable flags
Define new macro I_ERR_ODD_INODE_FLAGS to represents odd inode flags.
Symlinks should never have append/immutable flags.
While processing inodes, if found a symlink with append/immutable
flags, mark the inode record with I_ERR_ODD_INODE_FLAGS.
This is for original mode.
Issue: #133
