xive: Only set source type for LSIs

Browse source 
MSI is the default and LSI specific code is guarded by the
xive_source_irq_is_lsi() helper. The xive_source_irq_set()
helper is a nop for MSIs.

Simplify the code by turning xive_source_irq_set() into
xive_source_irq_set_lsi() and only call it for LSIs. The
call to xive_source_irq_set(false) in spapr_xive_irq_free()
is also a nop. Just drop it.
