passthroughLimit is being calculated even if usesVFIO is false.
After that, a if/else conditional is used to check if we're going
to sum it up with baseLimit.

This patch initializes passthroughLimit to zero and always
return memKB = baseLimit + passthroughLimit. The conditional
is then used to calculate passthroughLimit if usesVFIO is true.
This results in some cycles spared for the usesVFIO=false
scenario, but the real motivation is to make the code simpler
to add an alternative passthroughLimit formula for NVLink2
passthrough.

ACK to the idea, but looking at the number of lines of the PPC64 arch specific
logic (I know commentaries mostly), I think it deserves a separate helper to
enhance the readability.

You mean a 'static unsigned long long getPPC64MemLockLimit'  like function that
encapsulates the ppc64 logic? That can be arranged, no problem.
