ftrace: Fix char print issue in print_ip_ins()
When ftrace bug happened, following log shows every hex data in
problematic ip address:
actual: ffffffe8:6b:ffffffd9:01:21
But so many 'f's seem a little confusing, and that is because format
'%x' being used to print signed chars in array 'ins'. As suggested
by Joe, change to use format "%*phC" to print array 'ins'.
After this patch, the log is like:
actual: e8:6b:d9:01:21
