oocd_trace: fix warnings

gcc (Gentoo Hardened 4.6.3 p1.13) produces a warning about the variable
assigned but not used. write() can sometimes write less than the specified
count so it's marked with warn_unused_result in the system headers and its
return value can't be ignored. The most correct solution would be to have a
loop writing the buffer until all bytes are written or an error is
returned but here it's impractical.
