torture/ioctl: test set_compression(format_none)

This test case was overlooked in the previous bso#12144 update -
set compression requests with format=COMPRESSION_FORMAT_NONE should
succeed if the server / backing storage doesn't offer compression
support.
Confirm that Samba matches Windows Server 2016 ReFS behaviour here.
