[for-next][PATCH 6/7] tracing: Use __get_str() when manipulating strings

[Steven Rostedt <rostedt@goodmis.org>]

From: Daniel Bristot de Oliveira <bristot@redhat.com>

Use __get_str(str) rather than __get_dynamic_array(str) when
deadling with strings.

It is just a code cleanup, no changes on tracepoint ABI.
