eeprom: ee1004: Fix locking issues in ee1004_probe()
Currently, the devres-based management of ee1004_bus_data has
several issues when it comes to locking:
1. It does not call mutex_unlock() before returning an error.
2. When encountering an error, it deadlocks when trying to recursively
lock a mutex.
Fix this by moving the mutex-protected bus data initialization into
a separate function so that devm_add_action_or_reset() is called
without the mutex being held.
