EMLSR can't be activated from mac80211. Except for the debugfs, which is
intended for testing purposes. Currently we don't allow entering EMLSR
from debugfs if EMLSR is blocked, i.e. if mvmvif::esr_disable_reason is
not 0. But we need a way to activate EMLSR regardless of the vif being
blocked, for testing. Remove the check of esr_disable_reason
