[PATCH] jump_label: fix stack overflow

[Andrew Jones]

Fix a typo that leads to static_key_disable_cpuslocked infinitely
recursing.  This was found when the PMU kvm-unit-tests test for ARM
crashed the host and bisection lead to 924726b2b5e5 "perf: Cure
hotplug lock ordering issues".  That commit was just the victim,
the culprit commit is identified below in 'Fixes'.

Fixes: fc932a0477d0 "jump_label: Provide static_key_[disable|/slow_dec]_cpuslocked()"
