[PATCH] acpi: resource: Use AE_ABORT_METHOD to terminate acpi_dev_get_resources()

[Daniel Scally]

Switching this function to AE_CTRL_TERMINATE broke the documented
behaviour of acpi_dev_get_resources() - AE_CTRL_TERMINATE does not, in
fact, terminate the resource walk because acpi_walk_resource_buffer()
ignores it (specifically converting it to AE_OK), referring to that
value as "an OK termination by the user function". This means that
acpi_dev_get_resources() does not abort processing when the preproc
function returns a negative value.

Revert to AE_ABORT_METHOD
