Lucas De Marchi ae02c7b7fe drm/xe/rtp: Fix off-by-one when processing rules ...

Gustavo noticed an odd "+ 2" in rtp_mark_active() while processing
rtp rules and pointed that it should be "+ 1". In fact, while processing
entries without actions (OOB workarounds), if the WA is activated and
has OR rules, it will also inadvertently activate the very next
workaround.

Test in a LNL B0 platform by moving 18024947630 on top of 16020292621,
makes the latter become active:

	$ cat /sys/kernel/debug/dri/0/gt0/workarounds
	...
	OOB Workarounds
		18024947630
		16020292621
		14018094691
		16022287689
		13011645652
		22019338487_display

In future a kunit test will be added to cover the rtp checks for entries
without actions.
