ANDROID: debug_symbols: Add put_task_stack

Browse Source 
We need dump task->stack in kernel module for debug usage,
use try_get_task_stack to lock task->stack, and should call
put_task_stack to release.

Effective ABI change:

type 'enum android_debug_symbol' changed
  enumerator 'ADS_PUT_TASK_STACK' (21) was added
  enumerator 'ADS_END' value changed from 21 to 22
