Subject: [PATCH 3/6] [media] tda8261: Return directly after a failed kzalloc()
 in tda8261_attach()

* Return directly after a call of the function "kzalloc" failed
  at the beginning.

* Delete a call of the function "kfree" and the jump target "exit"
  which became unnecessary with this refactoring.
