m68k: Enable memtest functionality
Enable the memtest functionality and rearrange some code to prevent it
from clobbering the initrd.
The code to implement CONFIG_BLK_DEV_INITRD was conditional on
!defined(CONFIG_SUN3). For simplicity, remove that test on the basis
that m68k_ramdisk.size == 0 on Sun 3. The SLIME source code at
http://sammy.net/sun3/ftp/pub/m68k/sun3/slime/slime-2.0.tar.gz
indicates that no BI_RAMDISK entry is ever passed to the kernel due
to #ifdef 0 around the relevant code.
