Daniel Okazaki c850f71fca eeprom: at24: fix memory corruption race condition
[ Upstream commit f42c97027f ]

If the eeprom is not accessible, an nvmem device will be registered, the
read will fail, and the device will be torn down. If another driver
accesses the nvmem device after the teardown, it will reference
invalid memory.

Move the failure point before registering the nvmem device.
