perf probe: Fix probe_point buffer overrun

Fix probe_point array-size overrun problem. In some cases (e.g.
inline function), one user-specified probe-point can be
translated to many probe address, and it overruns pre-defined
array-size. This also removes redundant MAX_PROBES macro
definition.

[ Note that only root can create new probes. Eventually we should remove
  the MAX_PROBES limit, but that is a larger patch not eligible to
  perf/urgent treatment. ]
