    libgfapi: Gracefully exit when glfd is invalid

    This is a backport of: http://review.gluster.org/10759

    When glfs_* methods operating on glfd are invoked after calling
    glfs_close(), the program segfaults inside __GLFS_ENTRY_VALIDATE_FD
    trying to deference glfd->fd->inode which is invalid.

    Also, returning EBADF seemed more specific than EINVAL.
