qcacld-3.0: Add policy attribute to SET_TRACE_LEVEL

According to new changes in kernel 5.4 version onwards, driver has to
provide the policy for a NL command to be verified against while
registering wiphy to the kernel.

To satisfy kernel 5.4 requirement add policy to following vendor
command as part of this change:
	QCA_NL80211_VENDOR_SUBCMD_SET_TRACE_LEVEL
