Subject[PATCH] ubifs: Fix synced_i_size calculation for xattr inodes
In ubifs_jnl_update() we sync parent and child inodes to the flash,
in case of xattrs, the parent inode (AKA host inode) has a non-zero
data_len. Therefore we need to adjust synced_i_size too.

This issue was reported by ubifs self tests unter a xattr related work
UBIFS error (ubi0:0 pid 1896): dbg_check_synced_i_size: ui_size is 4, synced_i_size is 0, but inode is clean
UBIFS error (ubi0:0 pid 1896): dbg_check_synced_i_size: i_ino 65, i_mode 0x81a4, i_size 4
