cifs: Fix struct FILE_ALL_INFO
struct FILE_ALL_INFO for level 263 (0x107) used by QPathInfo does not have
any IndexNumber, AccessFlags, IndexNumber1, CurrentByteOffset, Mode or
AlignmentRequirement members. So remove all of them.
Also adjust code in move_cifs_info_to_smb2() function which converts struct
FILE_ALL_INFO to struct smb2_file_all_info.
Fixed content of struct FILE_ALL_INFO was verified that is correct against:
* [MS-CIFS] section 2.2.8.3.10 SMB_QUERY_FILE_ALL_INFO
* Samba server implementation of trans2 query file/path for level 263
* Packet structure tests against Windows SMB servers
This change fixes CIFSSMBQFileInfo() and CIFSSMBQPathInfo() functions which
directly copy received FILE_ALL_INFO network buffers into kernel structures
of FILE_ALL_INFO type.
struct FILE_ALL_INFO is the response structure returned by the SMB server.
So the incorrect definition of this structure can lead to returning bogus
information in stat() call.
