[Crash-utility] [Crash-Utility][PATCH v2 04/13] Rename get_cpu_reg to get_current_task_reg

[Tao Liu <ltao@xxxxxxxxxx>]

Since we only leave one gdb thread, or 1 cpu thread, and can use cmd "set"
to switch task context by reusing the thread. So the word "get_cpu_reg",
which stands for "fetch registers' value for cpu thread x", is no longer
appropriate, better using "get_current_task_reg", which stands for "fetch
registers' value for the current task", and makes more sense.
