e2fsck: show size requested when memory allocation fails

"e2fsck: Can't allocate dx_block info array"
is only so helpful - it'd be nice to know how much it tried to allocate.

In particular, since I think malloc(0) can return NULL,
it'd be nice to know if maybe we passed in an uninitialized (or
0-initialized) size.
