kernel: sdram: do not use xalloc for SDev

This was a sleeping bug, the unconfigure
routine was never called so the SDev structure
was never freed. Now that fshalt unconfigures the
drives before powering off, the fact that this was
alloc'd with xalloc causes a panic.
Found by sigrid, tested by sl and myself.
