If we want append hint to errp, we must use ERRP_FUNCTION_BEGIN macro.
Otherwise hint will not be appended in case of errp == &fatal_err
(program will exit before error_append_hint() call). Fix such cases.

This commit (together with its neighbors) was generated by

git grep -l 'error_append_hint(errp' | while read f; do \
spatch --sp-file scripts/coccinelle/fix-error_append_hint-usage.cocci \
--in-place $f; done

and then

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

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

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