This patch is based on Antti's silabs branch.
According to dvb-frontend.h set_frontend may be called with bandwidth_hz set to
0 if automatic bandwidth is required. Si2168 does not support automatic
bandwidth and does not declare FE_CAN_BANDWIDTH_AUTO in caps.
This patch will change the behaviour in a way that EINVAL is returned if
bandwidth_hz is 0.
v2: remove error message, remove line break to comply with coding style.
