patch 9.1.0128: win_gotoid() may abort even when not switching a window

Problem:  win_gotoid() checks for textlock and other things when switching
          to a window that is already current (after v9.1.0119)
Solution: return early with success when attempting to switch to curwin
          (Sean Dewar)

Other potential causes of E565 from win_gotoid after v9.1.0119 should be
correct. Plugins can consider using win_execute() instead if they wish to
temporarily switch windows during textlock.

fixes: #14073
closes: #14074
