[PATCH 5/9] Remove bare "except" from disassembler.py

[Tom Tromey <tromey@adacore.com>]

flake8 complains about a bare "except" in disassembler.py.  In this
case, the code purports to guard against some kind of user error
involving data structure corruption.  I think it's better here to just
let the error occur -- py-disasm.c will show a stack trace in this
case.
