asoc: wcd-dsp-mgr: clear work queue for wcd dsp manager



wdsp_mgr_bind would schedule work to load wdsp firmware.
Before loading wdsp firmware, sound card registeration may fail.
wcd_dsp_cntl_deinit would get called to free cntl which would be used
in wdsp_load_fw_image which would cause kernel panic.
Clear work queue in wdsp_mgr_unbind to avoid kernel panic.
