Staging: rtl8723au: Use put_unaligned_le32



Introduce the use of function put_unaligned_le32.

A simplified version of Coccinelle semantic patch used -

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

- tmp = cpu_to_le32(y);

  <+... when != tmp
- memcpy(ptr, (T)&tmp, ...);
+ put_unaligned_le32(y,ptr);
  ...+>
? tmp = e

@@ type T; identifier tmp; @@

- T tmp;
...when != tmp
