Dhruba Borthakur 7730587120 Prevent segfault in OpenCompactionOutputFile 
Summary:
The segfault was happening because the program was unable to open a new
sst file (as part of the compaction) because the process ran out of
file descriptors.

The fix is to check the return status of the file creation before taking
any other action.

Program received signal SIGSEGV, Segmentation fault.
