[PATCH] ACPI: Remove acpi_pci_unbind missing data complaint

[Gary Hade]

From: Gary Hade <garyhade@us.ibm.com>

Remove acpi_pci_unbind missing data complaints

In cases where acpi_pci_bind() [drivers/acpi/pci_bind.c] does not
attach device data, acpi_pci_unbind() [drivers/acpi/pci_bind.c]
complains via an ACPI exception about the missing data when
the device is removed.  For example, acpi_pci_bind() does not
attach data for non-existent device functions so when the device
is removed using the ACPI PCI hotplug driver 'acpiphp' an ACPI
exception is logged for every non-existent function.  This patch
avoids the confusing log messages by removing the unnecessary
ACPI exception.
