libsystemd-id128.so) were merged into a single libsystemd.so library to
reduce code duplication and avoid cyclic dependencies.

Do not check code twice. JB#45370

See merge request !38

Due to a bug this checked security code twice when authentication was
successful. Instead of calling both checkCode and unlockWithCode it
should be calling only unlockWithCode and which itself is calling
checkCode.
