runtime(optwin): Fix E94 when searching for the option-window
Problem: When the parameter debug=msg is set and the command :option is
entered, error E94 will be displayed.
Solution: Add a check for the existence of the buffer before getting the
buffer number “option-window”.
Reproduce:
vim --clean -c "set debug=msg" -c "option"
Error detected while processing command line..script D:\Programs\Vim
im91\optwin.vim:
line 9: E94: No matching buffer for option-window
