ANDROID: Incremental fs: fix magic compatibility again
It's still magic number issue which cannot be compatible with
arm-32 platform, although we try to fix it in Iae4f3877444
("ANDROID: Incremental fs: magic number compatible 32-bit"),
there is still incompatible scenario, such as: get_incfs_node(),
it will return NULL then kernel exception will be trigger because
of NULL pointer access. (inode_set() -> get_incfs_node(), then used
node->xxx directly)
We change magic number directly, otherwise, we must fix above issues
one by one.
