drivers/net: Remove address use from assignments of function pointers

"foo = &function" is more commonly written "foo = function"

Done with coccinelle script:

// <smpl>
@r@
identifier f;
@@

f(...) { ... }

@@
identifier r.f;
@@

- &f
+ f
// </smpl>

drivers/net/tehuti.c used a function and struct with the
same name, the function was renamed.

Compile tested x86 only.
