[PATCH-for-5.1 v3 17/23] hw/dma/xilinx_axidma: Add missing error-propagation code

[Philippe Mathieu-Daudé]

Patch created mechanically by running:

  $ spatch \
    --macro-file scripts/cocci-macro-file.h --include-headers \
    --sp-file scripts/coccinelle/add-missing-error_propagate.cocci \
    --keep-comments --smpl-spacing --dir hw

Then review showed this file has a 'xilinx_axidma_realize_fail'
label that calls error_propagate().  Updated the patch to use
the label.

v2: New cocci patch generated both transformations
    (Peter noticed v1 only catched one)
