There is no need to populate an unused variable, even if the read is required.
Fixes the following W=1 kernel build warning(s):
drivers/scsi/pcmcia/nsp_cs.c: In function ‘nsp_cs_message’:
drivers/scsi/pcmcia/nsp_cs.c:143:2: warning: function ‘nsp_cs_message’ might be a candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format]
drivers/scsi/pcmcia/nsp_cs.c: In function ‘nsp_fifo_count’:
drivers/scsi/pcmcia/nsp_cs.c:692:24: warning: variable ‘dummy’ set but not used [-Wunused-but-set-variable]
