Now commit message is updated, new version is below:

     sysprof: fix a message with stop without run

     When sysprof is not started the function `misc.sysprof.stop()`
     reports that profiler is already running:

     | $ ./src/luajit -e 'print(misc.sysprof.stop())'
     | nil     profiler is running already     22

     The patch fixes that:

     | $ ./src/luajit -e 'print(misc.sysprof.stop())'
     | nil     profiler is not running         22

     Follows up tarantool/tarantool#781
