LU-1337 kernel: NETIF_F_NO_CSUM and LOOKUP_CONTINUE removed

LU-1337 kernel: NETIF_F_NO_CSUM and LOOKUP_CONTINUE removed

1. kernel: 3.3 removes NETIF_F_NO_CSUM feature bit
   (kernel commit 34324dc2bf27c1773045fea63cb11f7e2a6ad2b9)
   The only one place uses NETIF_F_NO_CSUM is to check
   "(caps & (NETIF_F_IP_CSUM | NETIF_F_NO_CSUM | NETIF_F_HW_CSUM))".
   Replace (NETIF_F_IP_CSUM | NETIF_F_NO_CSUM | NETIF_F_HW_CSUM)
   as NETIF_F_ALL_CSUM which was added since kernel 2.6.17
   (kernel commit 8648b3053bff39a7ee4c711d74268079c928a657)
2. Kernel 3.1 kills LOOKUP_CONTINUE, LOOKUP_PARENT is equivalent
   to it since that.
   See kernel commit 49084c3bb2055c401f3493c13edae14d49128ca0

Another minor change is adding "#include <linux/module.h>" to
libcfs/linux/linux-crypto-adler.c, linux-crypto-crc32.c.
