[PATCH] cifs: Fix endian types in struct rfc1002_session_packet

[Pali Rohár]

All fields in struct rfc1002_session_packet are in big endian. This is
because all NetBIOS packet headers are in big endian as opposite of SMB
structures which are in little endian.

Therefore use __be16 and __be32 types instead of __u16 and __u32 in
struct rfc1002_session_packet.
