[for-next][PATCH 05/18] RAS/tracing: Use trace_seq_buffer_ptr() helper instead of open coded

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

Use the helper function trace_seq_buffer_ptr() to get the current location
of the next buffer write of a trace_seq object, instead of open coding
it.

This facilitates the conversion of trace_seq to use seq_buf.
