wifi: mt76: mt7925: Skip scan process during suspend.

We are experiencing command timeouts because an upper layer triggers
an unexpected scan while the system/device is in suspend.
The upper layer should not initiate scans until the NIC has fully resumed.
We want to prevent scans during suspend and avoid timeouts without harming
power management or user experience.
