The test case injects an error in the server by deleting the
temporary file that it uses during the load data statement
execution. The error consisted of closing, deleting and setting
the file descriptor to -1 right before calling mysql_file_write.

Although, this error injection seems to work OK in Unix like
environments, in Windows, this would cause the server to hit an
assertion in 'my_get_open_flags':

  DBUG_ASSERT(fd >= MY_FILE_MIN && fd < (int)my_file_limit)

We fix this by changing the error injection to just call the
macro my_delete_allow_opened, instead of the close + delete + set
fd=-1. The macro deletes the file and is platform
independent. Additionally, this required some changes to how the
assertion is handled in the test case to make it cope with this
change.
