Currently, add_resource() returns 1 on success, even though its callers
only check for negative values. Instead, propagate the insert_resource()
result from add_resource() to align with standard kernel return-value
conventions (0 on success, negative errno on failure).
Use %pR to print the full resource range while at it.

Changes in v2:
- Use %pR to print the full resource range as suggested by Ben Dooks
- v1: https://lore.kernel.org/lkml/20260512124628.300360-3-thorsten.blum@linux.dev/
