From: Zhao Liu <zhao1....@intel.com> The error_vprepend() should use ERRP_GUARD() just as the documentation of ERRP_GUARD() says:
> It must be used when the function dereferences @errp or passes > @errp to error_prepend(), error_vprepend(), or error_append_hint(). Considering that error_vprepend() is also an API provided in error.h, it is necessary to add it to the description of the rules for using ERRP_GUARD().
