target: Fail XCOPY for non matching source + destination block_size
This patch adds an explicit check + failure for XCOPY I/O to source +
destination devices with a non-matching block_size.
This limitiation is currently due to the fact that the scatterlist
memory allocated for the XCOPY READ operation is passed zero-copy
to the XCOPY WRITE operation.
