staging: rtl8192e: remove two set but not used variables

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

 In function '_rtl92e_dm_tx_power_tracking_callback_tssi':
drivers/staging/rtl8192e/rtl8192e/rtl_dm.c:621:7:
 warning: variable 'bHighpowerstate' set but not used [-Wunused-but-set-variable]
 In function '_rtl92e_dm_rx_path_sel_byrssi':
drivers/staging/rtl8192e/rtl8192e/rtl_dm.c:1904:32:
 warning: variable 'cck_rx_ver2_min_index' set but not used [-Wunused-but-set-variable]

They are never used, so can be removed.
