[PATCH] net: tulip: avoid unused variable warning

[deller@kernel.org]

From: Helge Deller <deller@gmx.de>

When compiling with W=1 and CONFIG_TULIP_MWI=n one gets this warning:
 drivers/net/ethernet/dec/tulip/tulip_core.c: In function ‘tulip_init_one’:
 drivers/net/ethernet/dec/tulip/tulip_core.c:1309:22: warning: variable ‘force_csr0’ set but not used

Avoid it by annotating the variable __maybe_unused, which seems to be
the easiest solution.
