Zide Chen aef5a4fd29 hv: free ptdev device IRQs when shutting down VM
Currently ptdev_release_all_entries() calls ptirq_release_entry() to
release ptdev IRQs, which is not sufficient because free_irq() is not
included in ptirq_release_entry().

Furthermore, function ptirq_deactivate_entry() and ptirq_release_entry()
have lots of overlaps which make the differences between them are not
clear.

This patch does:

- Adds ptirq_deactivate_entry() call in ptdev_release_all_entries() if the
  irq has not already freed.

- Remove unnecessary code from ptirq_deactivate_entry() to make it do the
  exact opposite to function ptirq_activate_entry(), except that
  entry->allocated_pirq is not reset, which is not necessary.

- Added the missing del_timer() to ptirq_release_entry() to make it almost
  opposite to ptirq_alloc_entry(); Added memset() to clear the whole entry,
  which doesn't have impacts to the functionalities but keep the data structure
  clean.
