Madhavan Krishnan 5f2f9406ce test: Fixed the compilation issue ...

The return value of write() function is ignored, causing the following
compiler error|warning with gcc version 5.4

error: ignoring return value of 'ssize_t write(int, const void*, size_t)'

Fix this by storing the return value of write() and return a test error in
case of failure.
