readprofile: don't stop parsing at __init_end

Some architectures like ARM place __init_end before .text section.
If any function in .init section is hit while profiling, readprofile
stops at __init_end.  That means if we enable profiling at boot time,
the profiler probably hits init functions and readprofile does not
work well unless we reset profiling buffer with -r option.
