Subject: [PATCH 4/7] scsi: fas216: avoid fas216_log_setup for loadable module

We get a warning for the fas216 driver when it is compiled as
a loadable module, as the __setup() functions are never called
then:

scsi/arm/fas216.c:101:19: warning: 'fas216_log_setup' defined but not used [-Wunused-function]
 static int __init fas216_log_setup(char *str)

This adds an #ifndef MODULE around the definition to shut up
the warning and clarify for the reader when it is used or not.
