x86/srso: Remove 'pred_cmd' label
SBPB is only enabled in two distinct cases:
1) when SRSO has been disabled with srso=off
2) when SRSO has been fixed (in future HW)
Simplify the control flow by getting rid of the 'pred_cmd' label and
moving the SBPB enablement check to the two corresponding code sites.
This makes it more clear when exactly SBPB gets enabled.
