bcachefs: Fix nonce inconsistency in bch2_write_prep_encoded_data()
If we're moving an extent that was partially overwritten,
bch2_write_rechecksum() will trim it to the currenty live range.
If we then also want to compress it, it'll be decrypted - but the nonce
has been advanced for the overwritten start of the extent that we
dropped, and we were using the nonce we calculated before rechecksum().
