Subject[PATCH] staging: vt6656: fix potential leak in vt6656_hostap_ioctl()
Commit fb841d67 (staging: vt6656: don't leak 'param' in vt6656_hostap_ioctl()
when returning -EOPNOTSUPP) cleaned up direct returns in the ioctl switch
statement that leaked already allocated memory. Fix the same issue for
VIAWGET_HOSTAPD_SCAN_REQ and VIAWGET_HOSTAPD_MLME that are also not supported
by this driver. Detected by Coverity - CID 144381.
