Andreas Hindborg 08f03186b9 null_blk: fix validation of block size ...

[ Upstream commit c462ecd659 ]

Block size should be between 512 and PAGE_SIZE and be a power of 2. The current
check does not validate this, so update the check.

Without this patch, null_blk would Oops due to a null pointer deref when
loaded with bs=1536 [1].
