Tetsuo Handa bc107a619f squashfs: verify inode mode when loading from disk ...

The inode mode loaded from corrupted disk might by error contain the file
type bits.  Since the file type bits are set by squashfs_read_inode()
using bitwise OR, the file type bits must not be set by
squashfs_new_inode() from squashfs_read_inode(); otherwise, an invalid
file type bits later confuses may_open().
