Subject: [PATCH 1/2] [media] it913x: Delete two error messages for a failed
 memory allocation in it913x_probe()

* Omit extra messages for a memory allocation failure in this function.

  This issue was detected by using the Coccinelle software.

* Delete the label "err" and the variable "ret" which became unnecessary
  with this refactoring.
