[PULL 46/48] hw/cxl: Fix msix_notify: Assertion `vector < dev->msix_entries_nr`

[Michael S. Tsirkin]

From: Li Zhijian <lizhij...@fujitsu.com>

This assertion always happens when we sanitize the CXL memory device.
$ echo 1 > /sys/bus/cxl/devices/mem0/security/sanitize

It is incorrect to register an MSIX number beyond the device's capability.

Increase the device's MSIX number to cover the mailbox msix number(9).

Fixes: 43efb0bfad2b ("hw/cxl/mbox: Wire up interrupts for background 
completion")
