dm: restrict dm device size to 2^63-512 bytes
[ Upstream commit 45fc728515c14f53f6205789de5bfd72a95af3b8 ]
The devices with size >= 2^63 bytes can't be used reliably by userspace
because the type off_t is a signed 64-bit integer.
Therefore, we limit the maximum size of a device mapper device to
2^63-512 bytes.
