x86/resctrl: Remove lockdep annotation that triggers false positive
get_domain_from_cpu() walks a list of domains to find the one that
contains the specified CPU. This needs to be protected against races
with CPU hotplug when the list is modified. It has recently gained
a lockdep annotation to check this.
The lockdep annotation causes false positives when called via IPI as the
lock is held, but by another process. Remove it.
[ bp: Refresh it ontop of x86/cache. ]
Fixes: fb700810d30b ("x86/resctrl: Separate arch and fs resctrl locks")
