crypto: qat - re-enable sriov after pf reset
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.
