From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The PI433_IOC_WR_RX_CFG case is missing a break and will fall through
to the default case and errorenously return -EINVAL. Fix this by
adding in missing break.
Detected by CoverityScan, CID#1461286 ("Missing break in switch")
Fixes: f81f0b5c9a30 ("pi433: sanitize ioctl")
