    [gdb/tui] Simplify tui_enable
    
    I noticed some code in tui_enable doing:
    ...
    if (...)
      error (...);
    else if (...)
    ...
    which is the "Don’t use else after a return" anti-pattern [1].
    
    Fix this by using:
    ...
    if (...)
      error (...);
    
    if (...)
    ...
