media: go7007: s2250: propagate control I/O failures
The brightness and contrast paths use oldvalue after read_reg_fp()
without checking whether the read succeeded. A failed read leaves
oldvalue uninitialized and can write arbitrary reserved register bits.
Return read and write errors from every control path so failed hardware
access cannot be reported as a successful control update.
