[libvirt] [PATCH v2 04/14] nodedev: Use switch for virNodeDeviceObjHasCap and virNodeDeviceCapMatch

[John Ferlan]

In order to ensure that whenever something is added to virNodeDevCapType
that both functions are considered for processing of a new capability,
change the if-then-else construct into a switch statement.
