The check for 1GB of available space in a DAX region always returned
true due to being wrapped inside a [[ ... ]] test, even when space
wasn't available. That caused set size to fail.

Update to use bash arithmetic evaluation instead.

This issue likely went unnoticed because users allocated >= 1GB of
efi_fake_mem. This fix is part of the transition to use CXL regions
in this test as efi_fake_mem support is being removed from the kernel.

Yikes, good find!
