When using the special SID to store the mode bits in an ACE (See http://technet.microsoft.com/en-us/library/hh509017(v=ws.10).aspx) which is enabled with mount parm "modefromsid" we were not passing in the mode via SMB3 create (although chmod was enabled). SMB3 create allows a security descriptor context to be passed in (which is more atomic and thus preferable to setting the mode bits after create via a setinfo). This patch enables setting the mode bits on create when using modefromsid mount option. In addition it fixes an endian error in the definition of the Control field flags in the SMB3 security descriptor. It also makes the ACE type of the special SID better match the documentation (and behavior of servers which use this to store mode bits in SMB3 ACLs).
