eeprom: at24: Use dev_err_probe for nvmem register failure

Browse Source 
[ Upstream commit a3c10035d1 ]

When using nvmem layouts it is possible devm_nvmem_register returns
-EPROBE_DEFER, resulting in an 'empty' in
/sys/kernel/debug/devices_deferred. Use dev_err_probe for providing
additional information.
