V4L/DVB (10772): siano: prevent duplicate variable declaration

Fix the following build error:

drivers/media/dvb/siano/smsusb.o: In function `get_order':
include/asm-generic/page.h:10: multiple definition of `sms_dbg'
drivers/media/dvb/siano/sms1xxx.o:include/asm-generic/page.h:10: first defined here
drivers/media/dvb/siano/smsdvb.o: In function `get_order':
include/asm-generic/page.h:10: multiple definition of `sms_dbg'
drivers/media/dvb/siano/sms1xxx.o:include/asm-generic/page.h:10: first defined here

Thanks to Mauro Carvalho Chehab for his original patch to address this issue.
