uprobes/tracing: Kill the pointless seq_print_ip_sym() call
seq_print_ip_sym(ip) in print_uprobe_event() is pointless, kallsyms_lookup(ip) can not resolve a user-space address. Signed-off-by: Oleg Nesterov <oleg@redhat.com> Acked-by: Srikar Dronamraju <srikar@linux.vnet.ibm.com> Tested-by: Anton Arapov <anton@redhat.com>
