drivers/edac: cleanup workq ifdefs

The origin of this code comes from patches at sourceforge, that
allow EDAC to be updated to various kernels. With kernel version 2.6.20 a
new workq system was installed, thus the patches needed to be modified
based on the kernel version. For submitting to the latest kernel.org
those #ifdefs are removed
