  [RISCV] Fix address type in Zacas seq_cst atomic pattern (#190729)

The seq_cst pattern in AMOCASPat used (vt GPR:$addr) for the address
operand, while all other patterns (monotonic, acquire, release, acq_rel)
consistently use (XLenVT GPR:$addr). This would produce a wrong type for
the address when vt differs from XLenVT (e.g., amocas.d on RV32 where
vt=i64).
