LU-2634 ldiskfs: clear extent flag for fast symlink

Fast symlinks on MDT filesystems formatted with the "extents" feature
are created with EXT4_EXTENTS_FL. e2fsck considers this a corruption
and deletes the symlink.

The patch is to clear LDISKFS_INODE_EXTENTS flag in
osd_ldiskfs_writelink() just as ext4_symlink() does.
