Correctly copy sr_datafeed_meta in sr_packet_copy(). 

Commit 5801d558 replaced g_slist_copy_deep() by some incorrect code
that actually leaks the newly allocated memory, instead of doing
a deep copy.

This new version should be more correct, more concise, and it fixes
the following warning:

src/session.c: In function 'sr_packet_copy':
src/session.c:1025:38: warning: passing argument 2 of 'g_slist_foreach' from incompatible pointer type [-Wincompatible-pointer-types]
   g_slist_foreach(meta_copy->config, (GCopyFunc)copy_src, NULL);
