gfapi: Closed the logfile fd in glfs_fini

The logfile fd is not closed even after calling glfs_fini,
hence in smb mount if connection to glusterfs volume fails
at a point after the log file was opened, the fd would remain
open until the process dies.

This patch closes the logfile fd in glfs_fini.

gNFS: RFE for NFS connection behavior

Implement reconfigure() for NFS xlator so that volume set/reset wont
restart the NFS server process. But few options can not be reconfigured
dynamically e.g. nfs.mem-factor, nfs.port etc which needs NFS to be
restarted.
