The current crypto raw data vectors need to be extended to support
out of place processing. It is proposed to add additional desl_sgl
to provide details for destination sgl.
The same is also extended to support rte_security usecases, where
we need total data length to know how much additional memory space
is available in buffer other than data length so that driver/HW
can write expanded size data after encryption.
