qemu-xen: free all the pirqs for msi/msix when driver unload
Pirqs are not freed when driver unload, then new pirqs are allocated when
driver reload. This could exhaust pirqs if do it in a loop.
This patch fixes the bug by freeing pirqs when ENABLE bit is cleared in
msi/msix control reg.
There is also other way of fixing it such as reuse pirqs between driver reload,
but this way is better.
