ACPI / watchdog: Print out error number when device creation fails
If the platform device creation fails for whichever reason the driver
prints out something like:
[ 0.978837] ACPI: watchdog: Failed to create platform device
However, that is quite confusing and does not include any information
why it failed. To make it more understandable, reword it like:
[ 0.978837] ACPI: watchdog: Device creation failed: -16
Which tells that we failed to create the watchdog device because some of
the resources were already reserved (-EBUSY).
