selftests: ublk: fix unused_result error

Browse source

Commit 166b476b8d (selftests/ublk: add shared memory zero-copy
support in kublk, 2026-03-31) introduced a write(2), ignoring its
return value and thus causing an error, when building.

Fix this by using the common workaround "(void)!" to trick the
compiler the result is being used.
