arm64: context: Fix comments and remove pointless smp_wmb() The comments in the ASID allocator incorrectly hint at an MP-style idiom using the asid_generation and the active_asids array. In fact, the synchronisation is achieved using a combination of an xchg operation and a spinlock, so update the comments and remove the pointless smp_wmb().
