[Pure Storage] Fix QoS setting for cloned volumes

Volumes created from glance images on the source FlashArray using
volume cloning are not being assigned the correct QoS specifications
associated with the requested volume type.

This patch resolves that issue.

This patch is standalone for 2024.1 as the codebase changed
for 2024.2 and this bug is addressed in a seperate patch for
that release.
