cpu/intel/model_1067x: Check for lock bit on IA32_FEATURE_CONTROL
df7aecd "cpu/intel: Configure IA32_FEATURE_CONTROL for alternative
SMRR" introduced a regression because it unconditionally writes to
IA32_FEATURE_CONTROL, which if it is already locked results in an
unhandled exception. The lock bit is already set on a system reboot.
