[PATCH] arm64/ptrace: Fix an error handling path in sve_set_common()

[Christophe JAILLET]

All error handling paths go to 'out', except this one. Be consistent and
also branch to 'out' here.

/!\ Speculative /!\

   This patch is based on analysis of the surrounding code and should be
   reviewed with care !

   If the patch is wrong, maybe a comment in the code could explain why.
