char: xilinx_devcfg: Fix regression

Fixed regression introduced by remove volatile in
'a920e66a043 ("char: xilinx_devcfg: Fix warnings in the driver")'

removed volatile around dma_done and error_status without further actions.
This fix prevents these variables from being optimized away without being
read.
