f2fs crypto: do not set encryption policy for non-directory by ioctl
Encryption policy should only be set to an empty directory through ioctl,
This patch add a judgement condition to verify type of the target inode
to avoid incorrectly configuring for non-directory.
Additionally, remove unneeded inline data conversion since regular or symlink
file should not be processed here.
