Subject: [PATCH v2 7/8] arm64: ftrace: Update stale comment

In commit:

  26299b3f6ba26bfc ("ftrace: arm64: move from REGS to ARGS")

... we folded ftrace_regs_entry into ftrace_caller, and
ftrace_regs_entry no longer exists.

Update the comment accordingly.

There should be no functional change as a result of this patch.
