[Alexander Vorwerk <alexander.vorwerk@stud.uni-goettingen.de>]

The following warnings showed up when compiling with W=1.

drivers/net/wireless/intel/iwlegacy/4965-rs.c: In function ‘il4965_rs_stay_in_table’:
drivers/net/wireless/intel/iwlegacy/4965-rs.c:1636:18: warning: variable ‘il’ set but not used [-Wunused-but-set-variable]
  struct il_priv *il;
                  ^~

  struct il_priv *il;

drivers/net/wireless/intel/iwlegacy/4965-rs.c: In function ‘il4965_rs_sta_dbgfs_scale_table_write’:
drivers/net/wireless/intel/iwlegacy/4965-rs.c:2535:18: warning: variable ‘il’ set but not used [-Wunused-but-set-variable]
  struct il_priv *il;
                  ^~

Fixing by removing the variables.
