media: tvp7002: fix uninitialized variable warning
tvp7002.c: In function 'tvp7002_g_register':
tvp7002.c:691:11: warning: 'val' may be used uninitialized in this function [-Wmaybe-uninitialized]
691 | reg->val = val;
| ~~~~~~~~~^~~~~
Just return without setting 'reg' if tvp7002_read returns an error.
