If the cipher name does not start with 'ecb(' we should bail out, as done
in the 'create()' function in 'crypto/xts.c'.

This patch is 100% speculative.
It is based on comparison with the 'create()' function from 'crypto/xts.c'
Code looks the same, but this aditionnal test is in xts.c and not in
lrw.c.
The 2 should maybe be consistent?
