[PULL 25/26] migration/multifd: Remove unnecessary usage of local Error

[peterx@redhat.com]

From: Avihai Horon <avihaih@nvidia.com>

According to Error API, usage of ERRP_GUARD() or a local Error instead
of errp is needed if errp is passed to void functions, where it is later
dereferenced to see if an error occurred.

There are several places in multifd.c that use local Error although it
is not needed. Change these places to use errp directly.
