KVM: Don't WARN if updating IRQ bypass route fails

Browse Source 
Don't bother WARNing if updating an IRTE route fails now that vendor code
provides much more precise WARNs.  The generic WARN doesn't provide enough
information to actually debug the problem, and has obviously done nothing
to surface the myriad bugs in KVM x86's implementation.

Drop all of the associated return code plumbing that existed just so that
common KVM could WARN.
