gpu: nvgpu: Return gr_ctx_resident from NVGPU_DBG_GPU_IOCTL_REG_OPS

NVGPU_DBG_GPU_IOCTL_REG_OPS currently doesn't return if the ctx was
resident in engine or not.

Regops are broken down into batches of 128 and each batch is executed
together. Since there only 32 bits were available in IOCTL args, returning
is ctx was resident isn't possible for all batches.
Hence return if the ctx was resident for the first batch.
