qcacmn: Add policy for QCA_NL80211_VENDOR_SUBCMD_SPECTRAL_SCAN_GET_STATUS

Vendor commands using nested attributes should use properly defined
policies instead of RAW_DATA and the same has been enforced since 5.4
kernel. Hence, defined a policy for the vendor command
QCA_NL80211_VENDOR_SUBCMD_SPECTRAL_SCAN_GET_STATUS.
