[PGO] Fix incorrect function entry count
...
Function entry count might be zero after the profile counts reset and
before reentry to the function.
Zero profile entry count is very bad as the profile count from BFI will
be wrong.
A simple fix is to set the profile entry count to 1 if there are
non-zero profile counts in this function.
