Anatol Belski e067c76880 tests: windows: Disable sparse for DM snapshot OS disks
The Windows tests use a DM snapshot device for the OS disk.
DM snapshot targets do not support BLKDISCARD, so the VMM returns
IOERR for every TRIM attempt. viostor.sys may BSOD when the host
returns an error for negotiated discard/write-zeroes operations.

Add a default_disks_sparse_off() helper to GuestCommand and use it
in all Windows tests.
