[media] drivers/media/dvb/ttpci/av7110_av.c: Add missing error handling code
Extend the error handling code with operations found in other nearby error
handling code.
A simplified version of the sematic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@r exists@
@r@
statement S1,S2,S3;
constant C1,C2,C3;
@@
*if (...)
{... S1 return -C1;}
...
*if (...)
{... when != S1
return -C2;}
...
*if (...)
{... S1 return -C3;}
// </smpl>
