bug: Error on Apply action in Avante Ask: 'winfixbuf' is enabled

Describe the bug

When using Avante Ask, and hitting either a or A to apply changes, I got the following error.

Error executing vim.schedule lua callback: ...al/share/nvim/lazy/avante.nvim/lua/avante/utils/init.lua:712: E1513: Cannot switch buffer.
'winfixbuf' is enabled
stack traceback:
        [C]: in function 'nvim_set_current_buf'
        ...al/share/nvim/lazy/avante.nvim/lua/avante/utils/init.lua:712: in function 'get_or_create_buffer_with_filepath'
        ...local/share/nvim/lazy/avante.nvim/lua/avante/sidebar.lua:562: in function ''
        vim/_editor.lua: in function ''
        vim/_editor.lua: in function <vim/_editor.lua:0>

I then ran :set nowinfixbuf in the LLM response window and Avante resumed operation there instead of in the main window. https://neovim.io/doc/user/message.html#E1513

Note that this option is probably incorrect: we don't want to modify the response buffer, but to switch to the main buffer and edit the code there. So, this is probably a bug in buffer selection.
