Subject: vDPA/ifcvf: decouple config IRQ releaser from the adapter
From: Zhu Lingshan <lingshan.zhu@xxxxxxxxx>
commit 23dac55cec3afdbc1b4eaed1c79f2cee00477f8b upstream.
This commit decouples config IRQ releaser from the adapter,
so that it could be invoked once probe or in err handlers.
ifcvf_free_irq() works on ifcvf_hw in this commit
