vim-patch:8.2.2776: :mksession uses current value of 'splitbelow' and 'splitright' (#14398)

Browse Source 
Problem:    :mksession uses current value of 'splitbelow' and 'splitright'
            even though "options" is not in 'sessionoptions'. (Maxim Kim)
Solution:   Save and restore the values, instead of setting to the current
            value. (closes vim/vim#8119)
0995c81f2f

Patch v8.2.1682 is not ported.
Replace "goto fail;" with "return FAIL;".
