We also move the assignment of -1 to the lock file descriptor
up, so that rollback_lock_file() can be called safely after a
possible attempt to fclose(). This matches the contents of
the 'if' statement just above testing success of fdopen().

Since we forget the lock file descriptor there is a chance
that we will leave the file open if a write error occurs. We'll
still delete the file. I don't think it's worth bending
over backwards to make sure the file is closed on this failure.
