[patch v2] [media] saa7164: fix endian conversion in saa7164_bus_set()

[Dan Carpenter]

The msg->command field is 32 bits, and we should fill it with a call
to cpu_to_le32().  The current code is broke on big endian systems.
On little endian systems it truncates the 32 bit value to 16 bits
which probably still works fine.

v2: Mauro pointed out that I missed the conversion back to cpu endian.

This is a static checker bug.  The current code is definitely broken on
big endian systems.  I'm pretty sure my fix is correct, but I don't
have the hardware to test it.
