Bluetooth: length variable inconsistency in keys.c

[jhedberg]

After commit 94451b2 there's an inconsistency with length variable usage:

zephyr/subsys/bluetooth/host/keys.c

Lines 339 to 341 in c635f4c

	if (len_rd != BT_KEYS_STORAGE_LEN) {
	BT_ERR("Invalid key length %zu != %zu", len,
	BT_KEYS_STORAGE_LEN);

Is the if-statement wrong in using len_rd or is the log message wrong in using len?

Unfortunately @fnde-ot is out for the next 2 weeks. But he had left this comment about this: 94451b2#r34438851

@jhedberg I bounce this issue back at you as we cannot expect @fnde-ot to react any time soon.

Fixed as a sideeffect of #19407
