V4L/DVB: az6027: remove redundant condition check

The condition (msg[i].addr == 0xd0) is checked twice the second one
is not necessary.

This will remove the following compiler warning:
   az6027.c: In function 'az6027_i2c_xfer':
   az6027.c:942: warning: 'index' may be used uninitialized in this function
   az6027.c:943: warning: 'value' may be used uninitialized in this function
   az6027.c:944: warning: 'length' may be used uninitialized in this function
   az6027.c:945: warning: 'req' may be used uninitialized in this function
