lttng-modules: Upgrade to 2.9.5 release

This upgrade is critical as it fixes the support for Linux 4.14 LTS kernel.

The changlog is:

2017-10-05 LTTng modules 2.9.5
	* Fix: update block instrumentation for 4.14 kernel
	* Revert "Fix: update block instrumentation for kernel 4.14"

2017-10-03 (National Techies Day) LTTng modules 2.9.4
	* Fix: version check error in btrfs instrumentation
	* Fix: update btrfs instrumentation for kernel 4.14
	* Fix: update writeback instrumentation for kernel 4.14
	* Fix: update block instrumentation for kernel 4.14
	* Fix: vmalloc wrapper on kernel < 2.6.38
	* Fix: vmalloc wrapper on kernel >= 4.12
	* Add kmalloc failover to vmalloc
	* Fix: mmap: caches aliased on virtual addresses
	* Fix: update ext4 instrumentation for kernel 4.13
	* Fix: Sleeping function called from invalid context
	* Fix: sched for v4.11.5-rt1
	* Fix: handle missing ftrace header on v4.12

This also removes the previously backported patches as they are part
of 2.9.4 release and the missing fix is part of 2.9.5 release.
