Do not batch close gofer.handle in lisafs.

In some scenarios, these handles are backed by open FDs to FIFO files. We can
not delay closing of such handles because application behavior depends on the
FD being closed immediately. For example, for pipes, when the write end is
closed, then read(2) on the read end will return 0 indicating that there are no
writers.
