patch 8.0.0224: change to 'fileformats' from autocmd does not take effect

Browse Source 
Problem:    When 'fileformats' is changed in a BufReadPre auto command, it
            does not take effect in readfile(). (Gary Johnson)
Solution:   Check the value of 'fileformats' after executing auto commands.
            (Christian Brabandt)
