Retry on ENODATA errors

A particular device in a particular system is known to fail
with an ENODATA errno when another entity is using the same
path to access it.  Add it to the retry list so that
phosphor-hwmon will retry and hopefully be able to get a
clean read.  Even for devices where this contention isn't
the case, the code may as well retry as opposed to trying
once and giving up.

Resolves openbmc/openbmc#2645
