staging: wfx: standardize the error when vif does not exist
Smatch complains:
drivers/staging/wfx/hif_rx.c:177 hif_scan_complete_indication() warn: potential NULL parameter dereference 'wvif'
drivers/staging/wfx/data_tx.c:576 wfx_flush() warn: potential NULL parameter dereference 'wvif'
Indeed, if the vif id returned by the device does not exist anymore,
wdev_to_wvif() could return NULL.
In add, the error is not handled uniformly in the code, sometime a
WARN() is displayed but code continue, sometime a dev_warn() is
displayed, sometime it is just not tested, ...
This patch standardize that.
