Douglas Miller 629e052d0c RDMA/hfi1: Prevent panic when SDMA is disabled 
If the hfi1 module is loaded with HFI1_CAP_SDMA off, a call to
hfi1_write_iter() will dereference a NULL pointer and panic. A typical
stack frame is:

  sdma_select_user_engine [hfi1]
  hfi1_user_sdma_process_request [hfi1]
  hfi1_write_iter [hfi1]
  do_iter_readv_writev
  do_iter_write
  vfs_writev
  do_writev
  do_syscall_64

The fix is to test for SDMA in hfi1_write_iter() and fail the I/O with
EINVAL.
