gdbserver: by-pass regcache to access tdesc only
The `get_thread_regcache` function has a `fetch` option to skip
fetching the registers from the target. It seems this option is set
to false only at uses where we just need to access the tdesc through
the regcache of the current thread, as in
struct regcache *regcache = get_thread_regcache (current_thread, 0);
... regcache->tdesc ...
Since the tdesc of a regcache is set from the process of the thread
that owns the regcache, we can simplify the code to access the tdesc
via the process, as in
... current_process ()->tdesc ...
This is intended to be a refactoring with no behavioral change.
Tested only for the linux-x86-low target.
