Alexander Shishkin cf302bfdf3 perf/x86/intel/pt: Document pt_buffer_reset_markers() 
The comments in the driver don't make it absolutely clear as to what
exactly is the calling order and other possible constraints of buffer
management functions.

Document constraints and calling order for the buffer configuration
functions. While at it, replace a redundant check in
pt_buffer_reset_markers() with an explanation why it is not needed.
