PCI: rcar: Remove IRQ mappings in rcar_pcie_enable_msi() failpath
The rcar_pcie_enable_msi() creates IRQ mappings using irq_create_mapping()
before requesting the IRQs using devm_request_irq(). If devm_request_irq()
fails for some reason, rcar_pcie_enable_msi() does not remove the mapping.
Pull out the code for disposing IRQ mappings from rcar_pcie_teardown_msi()
into a separate function and call it from both rcar_pcie_teardown_msi()
and rcar_pcie_enable_msi() failpath to remove the mappings correctly.
