Laurent Dufour c18956e6e0 powerpc/pseries: Fix update of LPAR security flavor after LPM 
After LPM, when migrating from a system with security mitigation enabled
to a system with mitigation disabled, the security flavor exposed in
/proc is not correctly set back to 0.

Do not assume the value of the security flavor is set to 0 when entering
init_cpu_char_feature_flags(), so when called after a LPM, the value is
set correctly even if the mitigation are not turned off.

Fixes: 6ce56e1ac3 ("powerpc/pseries: export LPAR security flavor in lparcfg")
