rseq: Fix rseq registration with CONFIG_DEBUG_RSEQ
With CONFIG_DEBUG_RSEQ=y, at rseq registration the read-only fields are
copied from user-space, if this copy fails the syscall returns -EFAULT
and the registration should not be activated - but it erroneously is.
Move the activation of the registration after the copy of the fields to
fix this bug.
Fixes: 7d5265ffcd8b ("rseq: Validate read-only fields under DEBUG_RSEQ config")
