rseq: Clarify rseq registration rseq_size bound check comment

Browse source

[ Upstream commit 26d43a90be ]

The rseq registration validates that the rseq_size argument is greater
or equal to 32 (the original rseq size), but the comment associated with
this check does not clearly state this.

Clarify the comment to that effect.
