tracing: Add trace_seq_buffer_ptr() helper function
There's several locations in the kernel that open code the calculation
of the next location in the trace_seq buffer. This is usually done with
p->buffer + p->len
Instead of having this open coded, supply a helper function in the
header to do it for them. This function is called trace_seq_buffer_ptr().
