Deleted a line that makes rocprof abort when using fine grained control one several APIs at a time. The parsing function in libtracer_tool.so that parses the input XML file that specifies the functions for which the user wants to activate the tracing callbacks seems to handle correctly cases where fine-grained control is used on several APIs. This line can be safely deleted.

Isolated flushing instructions into a wrapping function. The file descriptor used for flushing is the one that is globally defined and not the one stored in the context_entry_t object as it is always the one that is defined globally that is used. If using a globally defined file descriptor is problematic (however it is the norm in the libtracer_tool.so library in ROCTracer) rather than passing it through arguments, the wrapping flushing function can be modified to take a void pointer. The file descriptor can then be passed through this pointer and be used in the default flushing function.
