target/sbc: Add sbc_dif_generate software emulation
This patch adds WRITE_INSERT emulation within target-core
using TYPE1 / TYPE3 PI modes in sbc_dif_generate() code.
This is useful in order for existing legacy fabrics that do not
support protection offloads to interact with backend devices that
currently have T10 PI enabled.
v2 changes:
- Rename to sbc_dif_generate() (Sagi)
