passthrough: fix some spinlock issues in vmsi

Apart from efficiency, I hasten to fix the assertion failure.

- acquire pcidevs_lock before calling pt_irq_xxx_bind_vtd
- allocate msixtbl_entry beforehand
- check return value from domain_spin_lock_irq_desc()
- typo: spin_unlock(&irq_desc->lock) ->
- spin_unlock_irq(&irq_desc->lock)
- acquire msixtbl_list_lock with irq_disabled
