Subject: [PATCH 1/9] um/drivers/vector_user: Delete unnecessary code in
 user_init_raw_fds()

From: Markus Elfring <elfring@...rs.sourceforge.net>

* One condition check could never be reached with a non-null pointer
  at the end of this function. Thus remove the corresponding statement.

* Delete an initialisation for the local variable "result"
  which became unnecessary with this refactoring.
