This series fixes a use-after-free on the workqueue during driver remove.

Patch 1 fixes a pre-existing deadlock between the PCI reset worker and
pdsc_remove() that was identified during review of v1.

Patch 2 is the reworked UAF fix that moves destroy_workqueue() after
pdsc_teardown() and adds proper work synchronization.

v2:
- Fix deadlock between pci_reset_thread and remove (new patch 1/2)
  found by sashiko AI review of v1
- Rework UAF fix: move destroy_workqueue() after pdsc_teardown()
  instead of setting wq to NULL (addresses NULL deref found by sashiko)
- Add cancel_work_sync() after free_irq() to drain ISR-queued work
- Reorder adminqcq/notifyqcq freeing to avoid accessing freed notifyqcq
