hw/cxl: Fix msix_notify: Assertion vector < dev->msix_entries_nr

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).
