libgfapi, timer: Fix a crash seen in timer when glfs_fini was invoked.

The crash is seen when, glfs_init failed for some reason
and glfs_fini was called for cleaning up the partial initialization.

The fix is in two folds:

1. In timer store and restore the THIS, previously
   it was being overwritten.
2. In glfs_free_from_ctx() and glfs_fini() check for
   NULL before destroying.
