panic: make_dev_alias_v: bad si_name

Getting the following panic on HPE system with HPE enclosure:

panic: make_dev_alias_v: bad si_name (error=22,
si_name=enc@n....../type@0/slot@1/elmdesc@{"Name":"DriveBay1"}/pass4)

db_trace_self_wrapper()
vpanic()
panic()
make_dev_alias_v()
make_dev_alias_p()
make_dev_physpath_alias()
pass_add_physpath()
taskqueue_run_locked()
taskqueue_thread_loop()
fork_exit()
fork_trampoline()

I have skipped typing all the frame information as the cause of panic
seems to be apparent -- enclosure replies with "Name":"DriveBay1" via
ses (it does the same weirdness for sensors and other elements), and
make_dev_alias_v() does not like the double quotes.  Probably we need to
sanitize the input somewhere?
