ext4: reject inodes with negative size
commit 7e6e1ef48fc02f3ac5d0edecbb0c6087cd758d58 upstream.
Don't load an inode with a negative size; this causes integer overflow
problems in the VFS.
[ Added EXT4_ERROR_INODE() to mark file system as corrupted. -TYT]
Fixes: a48380f769df (ext4: rename i_dir_acl to i_size_high)
