cxl: remove a dead branch 

In commit 14baf4d9c7 ("cxl: Add guest-specific code") the following code
was added:

	if (afu->crs_len < 0) {
		dev_err(&afu->dev, "Unexpected configuration record size value\n");
		return -EINVAL;
	}

However the variable `crs_len` is of type u64 and cannot be compared < 0.
Remove the dead code section. Fix the following warning treated as error
with W=1:

../drivers/misc/cxl/guest.c:919:19: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]
