error: Move ERRP_GUARD() to the beginning of the function

Browse Source 
Since the commit 05e385d2a9 ("error: Move ERRP_GUARD() to the beginning
of the function"), there are new codes that don't put ERRP_GUARD() at
the beginning of the functions.

As stated in the commit 05e385d2a9: "include/qapi/error.h advises to put
ERRP_GUARD() right at the beginning of the function, because only then
can it guard the whole function.", so clean up the few spots
disregarding the advice.
