staging: rtl8192u: ieee80211: replace init_timer by setup_timer

This patch replaces init_timer and the 2 step initialization of function
and data by setup_timer to make the code more concise.

The issue was discovered using the following coccinelle script:

@@
expression ds, e1, e2;
@@

-init_timer (&ds);
+setup_timer (&ds, e1, e2);
...
(
-ds.function = e1;
...
-ds.data = e2;
|
-ds.data = e2;
...
-ds.function = e1;
)
