First off the budget for eu funds that Poland will receive is settled till 2021.
And negotiations for the new budget will start in a year, and as said before, there is now a strong lobby for redirecting those funds to countries who have been burdened to pick up the tap for the rest of the EU in the refugee crisis.
Hence they can only push Poland so far before Poland says screw you and bam the principal and any future returns are over.
Doing so would be economic suicide for Poland. Poland exports and imports more to Germany than to its' next three trading partner, and with Brexit, this number might even become bigger. As you said, those structural funds are no gift, they are granted out of solidarity to help poorer countries develop their economies which benefits all trading partners in the long. But if Poland continues to spit on such solidarity for too long, it will become more difficult to justify it.

If even despite that migrants are let in you'll see direct actions like people blocking their buses, harassing them, perhaps even violence.
I trust that the majority of the Polish people would react in a rational manner once it has been pointed out to them that genuin refugees (from Syria) pose no threat to them. Sadly, so far PiS has not adressed the issue in a rational manner and instead used it to get some cheap brownie points with nationalists.
Personally if I were an Iraqi Tunisian etc Muslim Poland would be my last choice.
Genuine refugees will be happy to live in safety. Those who are not (like Tunisians) won't be part of the relocation program.
The eu wants to talk solidarity where were they when tens of thousands of Ukrainians were coming in daily to Poland? Why don't they relieve the pressure on poland?
Because unlike refugees from the Middle East who require language courses and education, those refugees are of great economic benefit to Poland:

Has Poland actively asked for help by relocating those refugees? Of course not, because it values their economic potential far too much.
