wifi: ath12k: fix link capable flags

By default driver supports intra-device SLO/MLO, the link capability flags
reflect this. When the QMI PHY capability learning fails driver not enable
the MLO parameter in the host capability QMI request message. In this case,
reset the device link capability flags to zero (SLO/MLO not support) to
accurately represent the capabilities.

Found in code review.
