Namhyung Kim 26353a61b9 perf hists: Fix an invalid memory free on he->branch_info ...

The branch info was allocated for the whole stack and passed matching
hist entry for each level during processing samples.  Thus when a hist
entry tries to free its branch info like in hists__collapse_insert_entry
it'll face following error.

  *** glibc detected *** perf: munmap_chunk(): invalid pointer: 0x00000000014e9d20 ***
  ======= Backtrace: =========
  /lib64/libc.so.6[0x387d47ae16]
  perf[0x4923bd]
  perf(cmd_report+0xd68)[0x432a08]
  perf[0x41a663]
  perf(main+0x58f)[0x419eaf]
  /lib64/libc.so.6(__libc_start_main+0xf5)[0x387d421735]
  perf[0x419f95]

Fix it by allocating and copying branch info for each new hist entry.
