riscv: vector: Fix data pointer constraints in context save/restore
The standard vector save/restore asm advances datap but declares it as
input-only. An inlined caller reusing the original pointer may therefore
use the advanced address instead.
Declare datap as read-write so the compiler can preserve the original
pointer when needed.
