gfapi/upcall: Ignore handle create failures

In "glfs_h_poll_cache_invalidation", we need to send upcall only if there
is a corresponding inode entry in the gfapi inode table for that handle.

That's because the application will have reference to the inode as long as
it operates on any handle. That means the only case in which we cannot find
inode is when the application has closed the handle (either as part of unlink
or for any other purpose). But since it will have no more references and will
not be interested in any upcall event for that handle, we can safely ignore such
cases.

Note: This will affect only that particular applicaiton process/local libgfapi
client.

This is backport of below mainline patch -
