Given that ERRNO_IS_DEVICE_ABSENT() also matches positive values, make sure this macro is not called with arguments that do not have errno semantics. In this case the arguments passed to ERRNO_IS_DEVICE_ABSENT() are the values returned by external cryptsetup functions sym_crypt_init_by_name() and sym_crypt_deactivate_by_name() which are not expected to return any positive values, but let's be consistent anyway and move ERRNO_IS_DEVICE_ABSENT() invocations to the branches where the return values are known to be negative.
