ksmbd: define SMB2_COMPRESSION_TRANSFORM_ID in fs/ksmbd/smb2pdu.h

hulk inclusion
category: bugfix
bugzilla: 189016, https://gitee.com/openeuler/kernel/issues/I7LU2S
CVE: NA

--------------------------------

In mainline, commit 0d35e382 ("cifs: Create a new shared file holding
smb2 pdu definitions") moved 'SMB2_COMPRESSION_TRANSFORM_ID' to
fs/smbfs_common/smb2pdu.h, commit 38c8a9a5 ("smb: move client and
server files to common directory fs/smb") moved fs/ksmbd to fs/smb/server
and included above smb2pdu.h.

Now we need to use 'SMB2_COMPRESSION_TRANSFORM_ID' in fs/ksmbd. But
backport all those patch is not a good iead. Just add the define in
fs/ksmbd/smb2pdu.h.
