When a Physical Function (PF) is reset, SR-IOV gets disabled, making the associated Virtual Functions (VFs) unavailable. Even after reset and using pci_restore_state, VFs remain uncreated because the numvfs still at 0. Therefore, it's necessary to reconfigure SR-IOV to re-enable VFs. This commit introduces the ADF_SRIOV_ENABLED configuration flag to cache the SR-IOV enablement state. SR-IOV is only re-enabled if it was previously configured. This commit also introduces a dedicated workqueue without `WQ_MEM_RECLAIM` flag for enabling SR-IOV during Heartbeat and CPM error resets, preventing workqueue flushing warning. This patch is based on earlier work done by Shashank Gupta.
