    cxgbe/iw_cxgbe: Initialize the vma correctly in c4iw_mmap.
    
    This fixes userspace RDMA applications that would fail due to mmap
    failure.  The driver's mmap routine would succeed but later the
    linux_compat.c mmap routine would fail because vma->vm_private_data
    wasn't set properly.
    
    This is catch-up with b633e08c705fe43180567eae26923d6f6f98c8d9.
