Staging: rtl8192u: Combine initialization using setup_timer 

Author: Somya Anand <somyaanand214@gmail.com>

The function setup_timer combines the initialization of a timer with the
initialization of the timer's function and data fields.

So, this patch combines the multiline code for timer initialization using the function
setup_timer. This issue is identified via coccinelle script.

@@
expression E1, E2, E3;
type T;
@@
- init_timer(&E1);
...
(
- E1.function = E2;
...
- E1.data = (T)E3;
+ setup_timer(&E1, E2, (T)E3);
|
- E1.data = (T)E3;
...
- E1.function = E2;
+ setup_timer(&E1, E2, (T)E3);
|
- E1.function = E2;
+ setup_timer(&E1, E2, 0);
)
