Mark Rutland 8b6e70fccf arm64: traps: correctly handle MRS/MSR with XZR 
Currently we hand-roll XZR-safe register handling in
user_cache_maint_handler(), though we forget to do the same in
ctr_read_handler(), and may erroneously write back to the user SP rather
than XZR.

Use the new helpers to handle these cases correctly and consistently.
