In some situations, a faulty AFU slice may create an interrupt storm,
rendering the machine unusable. Since these interrupts are informational
only, present the interrupt once, then mask it off to prevent it from
being retriggered until the card is reset.

Changelog:
v2
	Rebase against linux-next
The patch changelog shouldn't be part of the commit message - it should 
go under a "---" line after the sign-off so it doesn't get included in 
the final commit.

Also now that I've taken a second look, I think the summary line of the 
commit message could be more descriptive, something like:

"cxl: mask slice error interrupt after first occurrence"

or something to that effect?
