erofs: reduntant assignment in __erofs_get_meta_page()

As Joe Perches suggested [1],
 		err = bio_add_page(bio, page, PAGE_SIZE, 0);
-		if (unlikely(err != PAGE_SIZE)) {
+		if (err != PAGE_SIZE) {
 			err = -EFAULT;
 			goto err_out;
 		}

The initial assignment to err is odd as it's not
actually an error value -E<FOO> but a int size
from a unsigned int len.

Here the return is either 0 or PAGE_SIZE.

This would be more legible to me as:

		if (bio_add_page(bio, page, PAGE_SIZE, 0) != PAGE_SIZE) {
			err = -EFAULT;
			goto err_out;
		}
