`criu_check_version()` failure check missing

[eriksjolund]

The following code does not check whether an error occured

crun/src/libcrun/criu.c

Lines 544 to 545 in 4a26a1a

	if (! libcriu_wrapper->criu_check_version (LIBCRIU_MIN_VERSION))
	return crun_make_error (err, 0, "libcriu is too old");

See criu_check_version() header:

/*
 * Check if the version of the CRIU binary is at least
 * 'minimum'. Version has to be in the same format as
 * described for criu_get_version().
 *
 * Returns 1 if CRIU is at least 'minimum'.
 * Returns 0 if CRIU is too old.
 * Returns < 0 if there was an error.
 */
int criu_check_version(int minimum);

I noticed this when reading the source code.
