blktrace: extract duplidate code

Impact: cleanup

blk_trace_event_print() and blk_tracer_print_line() share most of the code.

   text    data     bss     dec     hex filename
   8605     393      12    9010    2332 kernel/trace/blktrace.o.orig
   text    data     bss     dec     hex filename
   8555     393      12    8960    2300 kernel/trace/blktrace.o

This patch also prepares for the next patch, that prints out BLK_TN_MESSAGE.
