logging: typecast to stop signed-unsigned comparison

Browse source 
If source_id is -1, which is a valid value, it will be
converted to unsigned since it's compared with an unsigned
which means it will be huge and asserts will trigger. To avoid
this, we typecast the unsigned part to signed.

Resolves #40115
