Runyu Xiao 3f92a64545 scsi: pm8001: Use rollback index when freeing MSI-X vectors 
pm8001_request_msix() unwinds previously registered handlers with
free_irq() when request_irq() fails. The rollback loop uses the failing
index i for every iteration instead of the already registered vector
index j.

That passes the wrong IRQ/dev_id pair to free_irq() and leaves the
earlier handlers installed. Use j for both pci_irq_vector() and the
matching irq_vector entry in the rollback loop.

Fixes: a76037ff34 ("scsi: pm8001: switch to pci_irq_alloc_vectors")
