vim-patch:8.1.0892: failure when closing a window when location list is in use

Browse Source 
Problem:    Failure when closing a window when location list is in use.
Solution:   Handle the situation gracefully. Make sure memory for 'switchbuf'
            is not freed at the wrong time. (Yegappan Lakshmanan,
            closes vim/vim#3928)
