dpa_offload: Fix compat mode IOCTL commands for IPSec sequence number management functions

The two functions that are managing the IPSec sequence numbers,
dpa_ipsec_sa_modify and dpa_ipsec_sa_request_seq_number, don't have
IOCTL support for working in compat mode (32bit user space applications
calling a 64bit kernel). This change adds this support.
