Gao Xiang 0c9b52bfee erofs: fix incorrect symlink detection in fast symlink

[ Upstream commit 9ed50b8231e37b1ae863f5dec8153b98d9f389b4 ]

Fast symlink can be used if the on-disk symlink data is stored
in the same block as the on-disk inode, so we don’t need to trigger
another I/O for symlink data.  However, currently fs correction could be
reported _incorrectly_ if inode xattrs are too large.

In fact, these should be valid images although they cannot be handled as
fast symlinks.

Many thanks to Colin for reporting this!

[ Note that it's a runtime misbehavior instead of a security issue. ]
