ionic: use ee->offset when returning sprom data

Browse source 
[ Upstream commit b096d62ba1323391b2db98b7704e2468cf3b1588 ]

Some calls into ionic_get_module_eeprom() don't use a single
full buffer size, but instead multiple calls with an offset.
Teach our driver to use the offset correctly so we can
respond appropriately to the caller.
