[ Upstream commit 9c6921121961cc0cecccb95652be6d98116f854b ]
The function iwl_mvm_can_enter_esr() is (among others) calculating if EMLSR mode is disabled due to BT coex by calling iwl_mvm_bt_coex_calculate_esr_mode(), then stores the decision in mvmvif::esr_disable_reason. But there is no need to calculate this every time iwl_mvm_can_enter_esr is called. Fix this by calculating it once after authorization, and in iwl_mvm_can_enter_esr only check mvmvif::esr_disable_reason.
