query fs info level 0x100

[Steve French]

Trying some xfstests to current Samba (master branch, Samba 4.21),
they fail because query fs info (level 0x100) is returning
STATUS_INVALID_INFO_CLASS) - this works to ksmbd and I thought it used
to work to Samba.   I do see the SMB3.1.1 opens with the POSIX open
context works - but the query fs info failing causes xfstests to fail.

Is that missing rom current mainline Samba?
