[PATCH] tests: HE: add a test for wifi generation on 2.4 GHz

[Johannes Berg]

From: Johannes Berg <johannes.berg at intel.com>

This was broken in the kernel in mac80211 for a while, until commit
780a8c9efc65 ("mac80211: do not disable HE if HT is missing on 2.4 GHz")
fixed it.

Add a test for wifi generation on 2.4 GHz in addition to the 5 GHz one.
