wifi: mwifiex: Remove WQ_HIGHPRI from main workqueue

Browse Source 
The MWIFIEX_WORK_QUEUE handles command and event processing, including
the commands used for scheduled scans.

Running this work on the high-priority worker pool can interfere with
latency-sensitive workloads. On an i.MX8MP-based audio system using an
88W8997, background scheduled scans caused audible glitches in USB
audio playback.

Remove WQ_HIGHPRI from the main workqueue so that command and scan
processing use the normal-priority worker pool.

Leave the RX and host MLME workqueues unchanged.
