[PATCH AUTOSEL 5.10 051/116] iwlwifi: mvm: avoid clearing a just saved session protection id

[Sasha Levin]

From: Shaul Triebitz <shaul.triebitz@xxxxxxxxx>

[ Upstream commit 8e967c137df3b236d2075f9538cb888129425d1a ]

When scheduling a session protection the id is saved but
then it may be cleared when calling iwl_mvm_te_clear_data
(if a previous session protection is currently active).
Fix it by saving the id after calling iwl_mvm_te_clear_data.
