smbd: implement access checks for SMB2-GETINFO as per MS-SMB2 3.3.5.20.1
The spec lists the following as requiring special access:
- for requiring FILE_READ_ATTRIBUTES:
FileBasicInformation
FileAllInformation
FileNetworkOpenInformation
FileAttributeTagInformation
- for requiring FILE_READ_EA:
FileFullEaInformation
All other infolevels are unrestricted.
We ignore the IPC related infolevels:
FilePipeInformation
FilePipeLocalInformation
FilePipeRemoteInformation
