staging: rtlwifi: base: Remove set but not used variables

Browse Source 
Fixes gcc '-Wunused-but-set-variable' warning:

drivers/staging/rtlwifi/base.c: In function 'rtl_tx_agg_stop':
drivers/staging/rtlwifi/base.c:1733:23: warning:
 variable 'tid_data' set but not used [-Wunused-but-set-variable]

drivers/staging/rtlwifi/base.c: In function 'rtl_check_beacon_key':
drivers/staging/rtlwifi/base.c:2474:5: warning:
 variable 'ds_param_len' set but not used [-Wunused-but-set-variable]

drivers/staging/rtlwifi/base.c:2472:5: warning:
 variable 'ht_oper_len' set but not used [-Wunused-but-set-variable]

drivers/staging/rtlwifi/base.c:2470:5: warning:
 variable 'ht_cap_len' set but not used [-Wunused-but-set-variable]

They are never used and can be removed.
