nmbd crashes if built with profiling enabled

[Richard Sharpe]

Hi folks,

If you enable profiling during configure, nmbd will crash when
running. This is not usually a problem since no one really needs
profiling, but still.

There is a missing #if WITH_PROFILE section similar to what there is
in source3/smbd/server.c
