SCSI: libiscsi: regression: fix header digest errors
commit 96b1f96dcab87756c0a1e7ba76bc5dc2add82b88 upstream.

[SCSI] libiscsi: don't increment cmdsn if cmd is not sent
in 2.6.32.
When I moved the hdr->cmdsn after init_task, I added
a bug when header digests are used. The problem is
that the LLD may calculate the header digest in init_task,
so if we then set the cmdsn after the init_task call we
change what the digest will be calculated by the target.
