bcachefs: Fix initialization of bch_write_op.nonce

Browse source

If an extent ends up with a replica that is encrypted an a replica that
isn't encrypted (due the user changing options), and then
copygc/rebalance moves one of the replicas by reading from the
unencrypted replica, we had a bug where we wouldn't correctly initialize
op->nonce - for each crc field in an extent, crc.offset + crc.nonce must
be equal.

This patch fixes that by moving op.nonce initialization to
bch2_migrate_write_init.
