x86: remove bogus 'pci=usepirqmask' suggestion when no irq is defined
This was harmless, but for the case of a device that had no irq pre-defined we would incorrectly suggest that "usepirqmask" might make a difference. It never would, and the message was just confusing people. Reported in the dmesg of Etienne Lorrain. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
