Log: MFC r362829: The "pid" field in the LinuxKPI task struct is typically set to the thread ID and not the process ID. Make sure the linux_task_exiting() function uses tdfind() to lookup the BSD procedure structure pointer by the "pid" field, and only fallback to pfind() when no match is found! This makes linux_task_exiting() in line with the rest of the code.
