Grow: refuse to grow a 0.90 array beyond 2TB

A kernel bug makes handling for arrays using more than 2TB per device
incorrect, and the kernel doesn't stop an array from growing beyond
any limit.
This is fixed in 3.1

So prior to 3.1, make sure not to ask for an array to grow bigger than
2TB per device.
