Staging: rtl8192u: Use put_unaligned_le16

Browse Source 
This patch introduces the use of function put_unaligned_le16.

This is done using Coccinelle and semantic patch used is as follows:

@@ identifier tmp; expression ptr; expression y,e; type T; @@

- tmp = cpu_to_le16(y);

  <+... when != tmp
- memcpy(ptr, (T)&tmp, ...);
+ put_unaligned_le16(y,ptr);
  ...+>
? tmp = e

@@ type T; identifier tmp; @@

- T tmp;
...when != tmp

Here, unnecessory comment after change is removed too.
This patch also fixes sparse warnings in file ieeee80211_softmac.c.
