4.13.0-rc4 sparc64: can't allocate MSI-X affinity masks for 2 vectors

[Meelis Roos <mroos@linux.ee>]

I noticed that in 4.13.0-rc4 there is a new error in dmesg on my sparc64 
t5120 server: can't allocate MSI-X affinity masks.

I do not know if the driver works since nothing is attached to the FC 
HBA at the moment, but from the error messages it looks like the driver 
fails to load.

I booted 4.12 and 4.11 - the red error is not there but the failure 
seems to be the same error -22:

Will try older kernels too if it is useful for bisection.

On an older sparc64 (t1-200) with 4.13.0-rc4, qla2xxx loads fine (nothing is attached there either):
