Only do so after a brief check if we are in a Jail or not. This fixes SMP, because apparently it is crashing when calling try_generate() from the SysFSGlobalInformation::refresh_data method, so the fix for this is to simply not do that inside the Process' Jail spinlock scope, because otherwise we will simply have a possible flow of taking multiple conflicting Spinlocks (in the wrong order multiple times), for the SysFSOverallProcesses generation code: Process::current().jail(), and then Process::for_each_in_same_jail being called, we take Process::all_instances(), and Process::current().jail() again. Therefore, we should at the very least eliminate the first taking of the Process::current().jail() spinlock, in the refresh_data method of the SysFSGlobalInformation class.
