PCI/MSI: Use __get_cached_msi_msg() instead of get_cached_msi_msg()
Both callers of get_cached_msi_msg() start with a struct irq_data pointer, look up the corresponding IRQ number, and pass it to get_cached_msi_msg(), which then uses irq_get_irq_data() to look up the struct irq_data again to call __get_cached_msi_msg(). Since we already have the struct irq_data, call __get_cached_msi_msg() directly and skip the lookup work done by get_cached_msi_msg(). No functional change.
