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).
