chore: disable memory monitor in test_attach_too_much_devices

Attaching a large number of devices (94) on aarch64 consumes significant
host memory, causing memory monitor checks to fail. Since this test
specifically validates behavior when exceeding device limits, memory
usage isn't relevant here.

Disable the memory monitor check to ensure the test passes consistently.
