rawdev: allow devices to skip extra memory allocation

Browse Source 
Some device drivers want to allocate their own private memory, and should
be allowed to do so. Therefore skip memory allocation and associated error
checks if zero-length private memory is requested.

While adjusting the code for new indent level, fix incorrect error
message.
