arm64: backtrace: Don't bother trying to unwind the userspace stack
commit 1e6f5440a6814d28c32d347f338bfef68bc3e69d upstream.
Calling dump_backtrace() with a pt_regs argument corresponding to
userspace doesn't make any sense and our unwinder will simply print
"Call trace:" before unwinding the stack looking for user frames.
Rather than go through this song and dance, just return early if we're
passed a user register state.
