Josh Poimboeuf 1be339b0dc x86/srso: Fix SBPB enablement for (possible) future fixed HW 
[ Upstream commit 1d1142ac51307145dbb256ac3535a1d43a1c9800 ]

Make the SBPB check more robust against the (possible) case where future
HW has SRSO fixed but doesn't have the SRSO_NO bit set.

Fixes: 1b5277c0ea0b ("x86/srso: Add SRSO_NO support")
