error: Drop a few superfluous ERRP_GUARD()

include/qapi/error.h on ERRP_GUARD():

 * It must be used when the function dereferences @errp or passes
 * @errp to error_prepend(), error_vprepend(), or error_append_hint().
 * It is safe to use even when it's not needed, but please avoid
 * cluttering the source with useless code.

Clean up some of this clutter.
