net/ibmvnic: Ignore H_FUNCTION return from H_EOI to tolerate XIVE mode
Reversion of commit 11d49ce9f7946dfed4dcf5dbde865c78058b50ab
(“net/ibmvnic: Fix EOI when running in XIVE mode.”) leaves us
calling H_EOI even in XIVE mode. That will fail with H_FUNCTION
because H_EOI is not supported in that mode. That failure is
harmless. Ignore it so we can use common code for both XICS and
XIVE.
