target: Fix alua_access_state attribute OOPs for un-configured devices
This patch fixes a OOPs where an attempt to write to the per-device
alua_access_state configfs attribute at:
/sys/kernel/config/target/core/$HBA/$DEV/alua/$TG_PT_GP/alua_access_state
results in an NULL pointer dereference when the backend device has not
yet been configured.
This patch adds an explicit check for DF_CONFIGURED, and fails with
-ENODEV to avoid this case.
