Theodore Ts'o 4db0d88e2e ext4: fix reading new encrypted symlinks on no-journal file systems 
On a filesystem with no journal, a symlink longer than about 32
characters (exact length depending on padding for encryption) could not
be followed or read immediately after being created in an encrypted
directory.  This happened because when the symlink data went through the
delayed allocation path instead of the journaling path, the symlink was
incorrectly detected as a "fast" symlink rather than a "slow" symlink
until its data was written out.

To fix this, disable delayed allocation for symlinks, since there is
no benefit for delayed allocation anyway.
