dmaengine: switchtec-dma: fix chan_status_irq cleanup on create() error
chan_status_irq stores an MSI-X vector index, but err_exit freed it
with plain free_irq() instead of pci_free_irq(), which would free the
wrong Linux IRQ. The guard also treated a valid vector index of 0 as
unset, skipping the free entirely in that case and leaving the handler
registered against soon-to-be-freed swdma_dev.
Initialize chan_status_irq to -1 and use the value being non-negative
to signal when to free it with pci_free_irq().
