libgfapi: Gracefully exit when glfd is invalid
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.
BUG: 1221008
