Correctly detect failure to delete bufferevent read-timeout event

Gilad Benjamini noted that we check the error code for deleting a
write-timeout event twice, and the read timeout not at all.  This
shouldn't be a bit problem, since it's really hard for a delete to
fail on a timeout-only event, but it's worth fixing.

Fixes bug 3046787
