When mana_serv_reset() calls mana_gd_suspend(), mana_gd_cleanup() destroys gc->service_wq. If the subsequent mana_gd_resume() fails with -ETIMEDOUT or -EPROTO, the code falls through to mana_serv_rescan() which triggers pci_stop_and_remove_bus_device(). This invokes the PCI .remove callback (mana_gd_remove), which calls mana_gd_cleanup() a second time, attempting to destroy the already- freed workqueue. Fix this by NULL-checking gc->service_wq in mana_gd_cleanup() and setting it to NULL after destruction.
