Possible small glitch on cholmod_analyze.c

[cmendestecgraf]

On cholmod_analyze.c, line 552 (version 7.8.3), Common->try_catch is set to true and later restored to false on line 785. That is not ok if the user has set the try_catch option to true as his configuration option. If I understood the purpose of try_catch correctly, a better option would be to save the old value before setting it to TRUE and restore it at line 785 to the old value, and not to false.
