Subject: [RFC PATCH 2/4] acpi: apei: Swap ghes_print_queued_estatus and ghes_proc_in_irq

Move ghes_print_queued_estatus() above ghes_proc_in_irq(). In a
subsequent patch, the NMI handler will be updated, and the print
functionality will be used in ghes_proc_in_irq.
This simply makes the subsequent diff look sane.
