msi: fix MSI vector limit check in msi_set_mask()

MSI supports a maximum of PCI_MSI_VECTORS_MAX vectors - from 0 to
PCI_MSI_VECTORS_MAX - 1.

msi_set_mask() was previously using PCI_MSI_VECTORS_MAX as the upper
limit for MSI vectors. Fix the upper limit to PCI_MSI_VECTORS_MAX - 1.

Fixes: Coverity CID 1490141
Fixes: 08cf3dc61199 vfio-user: handle device interrupts
