crypto: talitos - Endianess in current_desc_hdr()
current_desc_hdr() compares the value of the current descriptor
with the next_desc member of the talitos_desc struct.
While the current descriptor is obtained from in_be32() which
return CPU ordered bytes, next_desc member is in big endian order.
Convert the current descriptor into big endian before comparing it
with next_desc.
This fixes a sparse warning.
