gpu-compute: Explicitly set driver to nullptr in constructor
We have a fail_if in attachDriver to prevent driver from being
overwritten. However, the fail_if only checks for if the driver
is not nullptr.
Previously, in some cases driver was set to garbage, which made
the fail_if trip the first time we were assigning the driver.
This patch explicitly sets driver to nullptr in the constructor, thus
ensuring that it will be nullptr the first time we call attachDriver
