Wei Chen 858e97d795 media: dvb-usb: az6027: fix three null-ptr-deref in az6027_i2c_xfer() 
In az6027_i2c_xfer, msg is controlled by user. When msg[i].buf is null,
commit 0ed554fd769a ("media: dvb-usb: az6027: fix null-ptr-deref in
az6027_i2c_xfer()") fix the null-ptr-deref bug when msg[i].addr is 0x99.
However, null-ptr-deref also happens when msg[i].addr is 0xd0 and 0xc0.
We add check on msg[i].len to prevent null-ptr-deref.
