Ming-Hung Tsai 1fe8a0dbde [thin_check] Allow using --clear-needs-check and --skip-mappings together
Although it is not recommended to clear the flag without a full
examination, however, the usage has been documented as an approach
to reduce lvchange run time [1]. For the purpose of backward
compatibility and avoiding boot failure after upgrading thin_check [2],
the limitation is now removed.
