Your patch doesn't look right.  I think it is correct that
`show-paren-mode' indicates mismatches on escaped parentheses in
latex-mode, because according to the syntax table of latex-mode,
these parentheses are not matched.  So when you type in latex-mode,
for example, C-M-f (forward-sexp) on them, you will get the error
"Unbalanced parentheses".  `show-paren-mode' just indicates the same
fact in a more visible way.

So you rather may try to change the syntax table of latex-mode
to allow it matching such parentheses.
