[PATCH v3 2/8] arm64/signal: Update the comment in preserve_sve_context

[Mark Brown]

From: Julien Grall <julien.grall at arm.com>

The SVE state is saved by fpsimd_signal_preserve_current_state() and not
preserve_fpsimd_context(). Update the comment in preserve_sve_context to
reflect the current behavior.
