EDAC: Rework workqueue handling
Hide the EDAC workqueue pointer in a separate compilation unit and add accessors for the workqueue manipulations needed. Remove edac_pci_reset_delay_period() which wasn't used by anything. It seems it got added without a user with 91b99041c1d5 ("drivers/edac: updated PCI monitoring") Signed-off-by: Borislav Petkov <bp@suse.de>
