fix(api): nvim_win_set_buf(0, 0) fails if 'winfixbuf' is set #31576

Browse Source 
## Problem
With 'winfixbuf' enabled, `nvim_win_set_buf` and `nvim_set_current_buf` fail
even if targeting the already-current buffer.

    vim.wo.winfixbuf = true
    vim.api.nvim_win_set_buf(0, 0)
    vim.api.nvim_set_current_buf(0)

Solution:
Check for this condition.
