[PATCH 05/12] src: Convert some _virDomainSecDef::sectype checks to switch()

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

In a few instances there is a plain if() check for
_virDomainSecDef::sectype. While this works perfectly for now,
soon there'll be another type and we can utilize compiler to
identify all the places that need adaptation. Switch those if()
statements to switch().
