The dev_err_probe() doesn't do anything when error is '-ENOMEM'.
Therefore, remove the useless call to dev_err_probe(), and just
return the value instead.

There is this comment regarding dev_err_probe:

 * Using this helper in your probe function is totally fine even if @err
 * is known to never be -EPROBE_DEFER.
 * The benefit compared to a normal dev_err() is the standardized format
 * of the error code, which is emitted symbolically (i.e. you get "EAGAIN"
 * instead of "-35"), and having the error code returned allows more
 * compact error paths.

If you want this change you have please justify it better, i.e.
we don't need to print error message because ...
