Fixing compatibility issue with CUDA array interface

[lowener]

Closes #3576.

This PR is a fix for CUDA arrays that don't have the strides property or that set this property to None.
Since it seems to be compliant with CUDA array interface v2 we should be able to support it.

Just a comment about the comment, otherwise looks great, thanks @lowener !

I would just change the wording of the comment, since the spec doesn't require strides to be omitted for C contiguous arrays, but if the strides are not given or none, then the array is C-contiguous. So, a C-contiguous array can also have its strides set (correctly, implying its contiguity of course)

True, I fixed it
