riscv: propagate insert_resource result from add_resource

Browse Source 
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.
