Not all SMB2 operations require FILE_READ_ATTRIBUTES access and therefore do not automatically request for FILE_READ_ATTRIBUTES access in every one SMB2 CREATE command. This change allows to complete WRITE operation to a file when it does not grant FILE_READ_ATTRIBUTES permission and its parent directory does not grant READ_DATA permission (parent directory READ_DATA is implicit grant of child FILE_READ_ATTRIBUTES permission).
