igmp: remove exceptional & on function name

Author: Himangi Saraogi <himangi774@gmail.com>

In this file, function names are otherwise used as pointers without &.

A simplified version of the Coccinelle semantic patch that makes this
change is as follows:

// 
@r@
identifier f;
@@

f(...) { ... }

@@
identifier r.f;
@@

- &f
+ f
//
