scsi: target: Remove unused variable 'tpg'

Gcc reports warning as follows:

drivers/target/target_core_pr.c:1162:26: warning:
 variable 'tpg' set but not used [-Wunused-but-set-variable]
 1162 |  struct se_portal_group *tpg;
      |                          ^~~

After commit 63c9ffe473d3 ("scsi: target: Check enforce_pr_isids during
registration"), 'tpg' is never used. Remove it to avoid build warning.
