[PATCH v1 2/2] hw/mem/cxl_type3: allocate more vectors for MSI-X

[Hyeonggon Yoo]

commit 43efb0bfad2b ("hw/cxl/mbox: Wire up interrupts for background
completion") enables notifying background command completion via MSI-X
interrupt (vector number 9).

However, the commit uses vector number 9 but the maximum number of
entries is less thus resulting in error below. Fix it by passing
nentries = 10 when calling msix_init_exclusive_bar().

 # echo 1 > sanitize
 Background command 4400h finished: success
 qemu-system-x86_64: ../hw/pci/msix.c:529: msix_notify: Assertion `vector < 
dev->msix_entries_nr' failed.

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