PCI: xgene-msi: Fix race in installing chained irq handler
[ Upstream commit a93c00e5f975f23592895b7e83f35de2d36b7633 ]
Fix a race where a pending interrupt could be received and the handler
called before the handler's data has been setup, by converting to
irq_set_chained_handler_and_data().
See also 2cf5a03cb29d ("PCI/keystone: Fix race in installing chained IRQ
handler").
Based on the mail discussion, it seems ok to drop the error handling.
