wifi: mac80211: Rename and update IEEE80211_VIF_DISABLE_SMPS_OVERRIDE
EMLSR operation and SMPS operation cannot coexist. Thus, when EMLSR is
enabled, all SMPS signaling towards the AP should be stopped (it is
expected that the AP will consider SMPS to be off).
Rename IEEE80211_VIF_DISABLE_SMPS_OVERRIDE to IEEE80211_VIF_EML_ACTIVE
and use the flag as an indication from the driver that EMLSR is enabled.
When EMLSR is enabled SMPS flows towards the AP MLD should be stopped.
