[Outreachy kernel][PATCH] staging: rtlwifi: Unneeded function halbtc_get_wifi_rssi()

[Bhanusree Pola <bhanusreemahesh@gmail.com>]

In the function halbtc_get_wifi_rssi:

if and else are functionally identical.
Unneeded return variable undec_sm_pwdb.
Function not needed and so assigned value rtlpriv->dm.undec_sm_pwdb where
the function halbtc_get_wifi_rssi() is called.
