[PATCH] x86/apic: move probe_nr_irqs_gsi() into ioapic_init_mappings()

[dirk.brandewie@gmail.com]

From: Thomas Gleixner <tglx@linutronix.de>

It is called right after ioapic_init_mappings() and there are no other
users. Move into ioapic_init_mappings() so the declaration can disappear
and the function can become static.
