[PATCH] perf jvmti: Remove unnecessary ret variable in jvmti_write_code

[Luo Yifan]

Following the approach in the jvmti_write_debug_info function, just
remove the ret variable from jvmti_write_code function. It's safe since
we don’t really care about the return value of fwrite_unlocked. This
change makes the code cleaner and more compiler-friendly.
