eth: sun: cassini: remove dead code

commit 32329216ca1d6ee29c41215f18b3053bb6158541 upstream.

Fixes the following GCC warning:

drivers/net/ethernet/sun/cassini.c:1316:29: error: comparison between two arrays [-Werror=array-compare]
drivers/net/ethernet/sun/cassini.c:3783:34: error: comparison between two arrays [-Werror=array-compare]

Note that 2 arrays should be compared by comparing of their addresses:
note: use ‘&cas_prog_workaroundtab[0] == &cas_prog_null[0]’ to compare the addresses
