Fix macro error if QAT_DUMP is defined for debugging.

Use PCI_MSIX_"TBL"BIR_MASK instead of PCI_MSIX_"PBA"BIR_MASK for MSI-X table.
This is not a real bug because both macros have the same value.

Workaround for Atom C2000 series (Rangeley) qat, ok'ed by hikaru@n.o.

C2000 qat has two engines, however it doesn't have arbiter.
If we enable both engines, qat interrupts twice wrongly (and second
interrupt notice invalid data). So, we enable only one engine.

- Hide the details of SPCF_SHOULDYIELD and related behind a couple of small
functions: preempt_point() and preempt_needed().

- preempt(): if the LWP has exceeded its timeslice in kernel, strip it of
any priority boost gained earlier from blocking.
