UBIFS: fix memory leak on error path
UBIFS leaks memory on error path in 'ubifs_jnl_update()' in case of write failure because it forgets to free the 'struct ubifs_dent_node *dent' object. Although the object is small, the alignment can make it large - e.g., 2KiB if the min. I/O unit is 2KiB. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Cc: stable@kernel.org
