[PATCH 38/40] scsi: sym53c8xx_2: sym_hipd: Ensure variable has the same stipulations as code using it

[Lee Jones]

Only declare 'tp' and 'lp' if they are going to be used.

Fixes the following W=1 kernel build warning(s):

 drivers/scsi/sym53c8xx_2/sym_hipd.c: In function ‘sym_complete_error’:
 drivers/scsi/sym53c8xx_2/sym_hipd.c:5356:18: warning: variable ‘lp’ set but 
not used [-Wunused-but-set-variable]
 drivers/scsi/sym53c8xx_2/sym_hipd.c: In function ‘sym_complete_ok’:
 drivers/scsi/sym53c8xx_2/sym_hipd.c:5485:18: warning: variable ‘lp’ set but 
not used [-Wunused-but-set-variable]
