net: sundance: Replace one-element array with non-array object

It seems this one-element array is not actually being used as an
array of variable size, so we can just replace it with just a
non-array object of type struct desc_frag and refactor a bit the
rest of the code.

This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().

This issue was found with the help of Coccinelle and audited and fixed,
manually.
