arm64: Rename get_thread_info()
The assembly macro get_thread_info() actually returns a task_struct and is
analogous to the current/get_current macro/function.
While it could be argued that thread_info sits at the start of
task_struct and the intention could have been to return a thread_info,
instances of loads from/stores to the address obtained from
get_thread_info() use offsets that are generated with
offsetof(struct task_struct, [...]).
Rename get_thread_info() to state it returns a task_struct.
