[PULL 1/6] virtiofsd: Silence gcc warning

["Dr. David Alan Gilbert (git)" <dgilbert@redhat.com>]

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>

Gcc worries fd might be used unset, in reality it's always set if
fi is set, and only used if fi is set so it's safe.  Initialise it to -1
just to keep gcc happy for now.
