[PATCH 5.5 133/170] ieee80211: fix HE SPR size calculation

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@xxxxxxxxx>

commit 575a97acc3b7446094b0dcaf6285c7c6934c2477 upstream.

The he_sr_control field is just a u8, so le32_to_cpu()
shouldn't be applied to it; this was evidently copied
from ieee80211_he_oper_size(). Fix it, and also adjust
the type of the local variable.

Fixes: ef11a931bd1c ("mac80211: HE: add Spatial Reuse element parsing support")
