Masami Hiramatsu 0104fe69e0 perf probe: Remove bias offset to find probe point by address 
Remove bias offset to find probe point by address.

Without this patch, probe points on kernel and executables are shown
correctly, but do not work with libraries:

  # ./perf probe -l
    probe:do_fork        (on do_fork@kernel/fork.c)
    probe_libc:malloc    (on malloc in /usr/lib64/libc-2.17.so)
    probe_perf:strlist__new (on strlist__new@util/strlist.c in /home/mhiramat/ksrc/linux-3/tools/perf/perf)

Removing bias allows it to show it as real place:

  # ./perf probe -l
    probe:do_fork        (on do_fork@kernel/fork.c)
    probe_libc:malloc    (on __libc_malloc@malloc/malloc.c in /usr/lib64/libc-2.17.so)
    probe_perf:strlist__new (on strlist__new@util/strlist.c in /home/mhiramat/ksrc/linux-3/tools/perf/perf)
