Steven Rostedt 531ee10b43 tracing: Show function names when possible when listing fields 
When the "fields" option is enabled, the "print fmt" of the trace event is
ignored and only the fields are printed. But some fields contain function
pointers. Instead of just showing the hex value in this case, show the
function name when possible:

Instead of having:

 # echo 1 > options/fields
 # cat trace
 [..]
  kmem_cache_free: call_site=0xffffffffa9afcf31 (-1448095951) ptr=0xffff888124452910 (-131386736039664) name=kmemleak_object

Have it output:

  kmem_cache_free: call_site=rcu_do_batch+0x3d1/0x14a0 (-1768960207) ptr=0xffff888132ea5ed0 (854220496) name=kmemleak_object
