PCI: dra7xx: Fix threaded IRQ request for "dra7xx-pcie-main" IRQ

commit 03f84b3b upstream.

Commit da87d35a ("PCI: dra7xx: Use threaded IRQ handler for
"dra7xx-pcie-main" IRQ") switched from devm_request_irq() to
devm_request_threaded_irq() for the "dra7xx-pcie-main" interrupt.

Since the primary handler was set to NULL, the "IRQF_ONESHOT" flag
should have also been set. Fix this.
