[PATCH v4 22/31] XIVE: Fix error_append_hint/error_prepend usage

[Vladimir Sementsov-Ogievskiy]

If we want to add some info to errp (by error_prepend() or
error_append_hint()), we must use the ERRP_AUTO_PROPAGATE macro.
Otherwise, this info will not be added when errp == &fatal_err
(the program will exit prior to the error_append_hint() or
error_prepend() call).  Fix such cases.

This commit (together with its neighbors) was generated by

git grep -l 'error_\(append_hint\|prepend\)(errp' | while read f; do \
spatch --sp-file scripts/coccinelle/fix-error-add-info.cocci \
--in-place $f; done

and then

./python/commit-per-subsystem.py MAINTAINERS "$(< auto-msg)"

(auto-msg was a file with this commit message)

and then by hand, for not maintained changed files:

git commit -m "<SUB-SYSTEM>: $(< auto-msg)" <FILES>

Still, for backporting it may be more comfortable to use only the first
command and then do one huge commit.
