Subject: lsi53c895a: avoid a write only variable

Compiling with GCC 4.6.0 20100925 produced a warning:
/src/qemu/hw/lsi53c895a.c: In function 'lsi_do_msgout':
/src/qemu/hw/lsi53c895a.c:848:9: error: variable 'len' set but not used [-Werror=unused-but-set-variable]

Fix by adding a dummy cast so that the variable is not unused for
non-debug case.
