rdma_request() is supposed to return negative values on error.  This change
means that if a kmalloc() fails it returns -ENOMEM.  The original code returned
certain negative values, zero on success and zero on kmalloc() failures.

I was just reading the code and I noticed this bug.  I haven't tested it because I
don't have the hardware.
