[ Upstream commit c7803b05f74bc3941b127f3155671e1944f632ae ]
Fix an endian bug in ksmbd for one remaining use of Persistent/VolatileFid that unnecessarily converted it (it is an opaque endian field that does not need to be and should not be converted) in oplock_break for ksmbd, and move the definitions for the oplock and lease break protocol requests and responses to fs/smbfs_common/smb2pdu.h
Also move a few more definitions for various protocol requests that were duplicated (in fs/cifs/smb2pdu.h and fs/ksmbd/smb2pdu.h) into fs/smbfs_common/smb2pdu.h including:
- various ioctls and reparse structures - validate negotiate request and response structs - duplicate extents structs
