[for-next][PATCH 15/16] tracing: Use strscpy() instead of strcpy() in trace_sched_switch

[Steven Rostedt]

From: Po-Sheng Lin <posheng.lin.tw@xxxxxxxxx>

Replace strcpy() with strscpy() in __trace_find_cmdline() for
consistency with the existing strscpy() call in the same function,
and to avoid potential buffer overflow as flagged by the Kernel
Self Protection Project.
