ext4/046: skip test when ext4 doesn't support bs < ps with dioread_nolock

Browse Source 
When testing arm machine, this case fails because ps > bs and kernel
doesn't introduced commit c8cc88163f40 ("ext4: Add support for
blocksize < pagesize in dioread_nolock").  Only skip this case when
kernel complains about bs!=ps error, so we can find dioread_nolock
mount regression in the future.
