qcacld-3.0: Use right copy length for struct hecap_6ghz to avoid OOB

In function wlan_cfg80211_tdls_extract_6ghz_params(), the length of
req_info->he_6ghz_cap is two bytes, but with a copy length of the
length of pointer params->he_6ghz_capa. Make sure the righ copy
length is used here to avoid OOB.
