wifi: ath12k: Set up MLO after SSR

Browse Source 
During recovery of an MLO setup from a core reset,
ATH12K_GROUP_FLAG_REGISTERED is set because ath12k_mac_unregister is not
called during core reset. So, when an MLO setup is recovering from a core
reset, ath12k_core_mlo_setup() is skipped. Hence, the firmware will not
have information about partner links. This makes MLO association fail
after recovery.

To resolve this, call ath12k_core_mlo_setup() during recovery, to set up
MLO. Also, if MLO setup fails during recovery, call
ath12k_mac_unregister() and ath12k_mac_destroy() to unregister mac and
then tear down the mac structures.

Also, initiate MLO teardown in the hardware group stop sequence to align
with the hardware group start sequence.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01181-QCAHKSWPL_SILICONZ-1
