[PATCH] trivial: scripts_kernel-doc: ignoring embedded structs shouldn't be

From:  <adobriyan@mail.ru>

Imagine you have a code similar to

  struct foo {
  	union {
  		struct tcphdr   *th;
  	} h;
  	union {
  		struct iphdr    *iph;
  	} nh;
  };

kernel-doc in it's current state will happily eat everything from first '{' to
last '}' and nobody will see parameter 'h' in documentation (look at
include/linux/skbuff.h:struct sk_buff for real world example).

So, fix the greedy regexp.
