[PATCH] clk: Delete init for local variable "best_crent_rate".

[jiping huang]

  I'm sorry, my last submission may not expressed it clearly, and there \
is an error delete. Therefore, I would like to generate a new patch and \
explanations.
  Actually, it is, the local variable 'best_crent_rate' is only used in \
line 2355 for the judgment 'best_crent_rate!=parent ->rate'. However, \
if the "if (clk_core_can_round (core))" branch condition in line 2306 \
is true, the value of the local variable "best_crent_rate" will be \
updated by "best_crent_rate=req.best_crent_rate;" in line 2319, otherwise \
it will be directly returned in the "else if" branch in line 2325 and the \
"else" branch in line 2329.
  In summary, it is unnecessary to store the "parent ->rate" value in \
"best_crent_rate" in line 2301.
  Thank you for your precious time!
