smb: move SMB2 Status code to common header file

smb: move SMB2 Status code to common header file

There are only 4 different definitions between the client and server:

  - STATUS_SERVER_UNAVAILABLE: from client/smb2status.h
  - STATUS_FILE_NOT_AVAILABLE: from client/smb2status.h
  - STATUS_NO_PREAUTH_INTEGRITY_HASH_OVERLAP: from server/smbstatus.h
  - STATUS_INVALID_LOCK_RANGE: from server/smbstatus.h

Rename client/smb2status.h to common/smb2status.h, and merge the
2 different definitions of server to common header file.
