Fix bare except in Stream_accept that swallows all exceptions (#1631) (#1632)

Narrow the catch from bare `except: pass` to `except TypeError`
with a string check, so that only missing `__cuda_stream__` is
silently handled. Buggy protocol implementations and other
exceptions now propagate correctly.
