Horia Geantă 3032e10da7 MLK-25151 crypto: caam/jr - fix shared IRQ line handling 
There are cases when the interrupt status register (JRINTR) is non-zero,
even though there was no interrupt generated for the corresponding
job ring.

For example JRINTR=0x0000_0008 - i.e. JRINTR[HALT]=b'10 - indicates that
the input job ring underwent a flush of all on-going jobs and processing
of still-existing jobs (sitting in the ring) has been halted.
This doesn't mean there's currently anything to do for this job ring.

Make sure the shared IRQ line is correctly handled by updating
the condition for returning IRQ_NONE, otherwise we could reach situations
like:
1. interrupt handler clearing JRINTR (and thus also the JRINTR[HALT]
field) while corresponding job ring is suspended and then
2. that job ring failing on resume path, due to expecting
JRINTR[HALT]=b'10 and reading instead JRINTR[HALT]=b'00.
