mlxsw: spectrum: Fix EEPROM access in case of SFP/SFP+

The current code does not handle correctly the access to the upper page
in case of SFP/SFP+ EEPROM. In that case the offset should be local
and the I2C address should be changed.

Fixes: 2ea109039cd3 ("mlxsw: spectrum: Add support for access cable info via ethtool")
