fru-device: fix return value of i2cSmbusWriteThenRead()

It had been returning the number of messages exchanged, not the number
of bytes received.  At present this hasn't been causing any problems,
but some impending changes have some stricter requirements for the
return value of ReadBlockFunc functions that this wouldn't have matched.

Tested: on a Delta AHE-50DC, fru-device continued operating as before;
nothing broke.
