leansdr: Fix unsigned printf format specifiers

Browse Source 
Replace signed %ld format specifiers with unsigned %lu conversions when
printing values stored as unsigned long.

The previous format strings passed unsigned values to signed printf
conversions, which could result in undefined behavior due to variadic
argument type mismatches. These issues were identified by cppcheck
invalidPrintfArgType_sint warnings.

Use format specifiers matching the actual argument types to ensure
correct and portable printf usage.
