Fixing non-blocking parser reporting incorrect location when fed with non-zero offset

[iifawzi]

Hello, this PR is an attempt to resolve #1412
The issue with the changed line is that it was double counting the offset as _inputPtr keeps increasing

This change ensures we track the relative position of each token in the JSON input stream, rather than being affected by the absolute array indices used when feeding the data.

Thank you! I'll need to double-check change wrt rest of code but sounds legit.

Aside from that, one thing we'd need before merging in the fix is CLA:

https://github.com/FasterXML/jackson/blob/master/contributor-agreement.pdf

(unless you have sent one earlier)
which is needed before merging the first contribution. Usual way is to print it, fill & sign, scan/photo, email to cla at fasterxml dot com. Once we have it I can proceed and merge the fix.

Thank you in advance!

Thank you @cowtowncoder, I forgot to check the guide.
Signed and sent for jackson-core, and will make sure to send separate ones if touching any other projects.

Let me know if I can assist with any further verifications in any other repository.
