hv: ptirq: associate an irte with ptirq_remapping_info entry

Browse Source 
For a ptirq_remapping_info entry, when build IRTE:
- If the caller provides a valid IRTE, use the IRET
- If the caller doesn't provide a valid IRTE, allocate a IRET when the
entry doesn't have a valid IRTE, in this case, the IRET will be freed
when free the entry.
