media: dw2102: Fix use after free
dvb_usb_device_init stores parts of properties at d->props
and d->desc and uses it on dvb_usb_device_exit.
Free of properties on module probe leads to use after free.
Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=204597
The patch makes properties static instead of allocated on heap to prevent
memleak and use after free.
Also fixes s421_properties.devices initialization to have 2 element
instead of 6 copied from p7500_properties.
