[PATCH 1/2] x86/pci: Simplify is_mmconf_reserved() messages

[Bjorn Helgaas <helgaas@kernel.org>]

From: Bjorn Helgaas <bhelgaas@google.com>

is_mmconf_reserved() takes a "with_e820" parameter that only determines the
message logged if it finds the MMCONFIG region is reserved.  Pass the
message directly, which will simplify a future patch that adds a new way of
looking for that reservation.  No functional change intended.
