User fence syncpt_id in the buffer compbits state was set to 0 on allocation through PREPARE_COMPRESSIBLE_READ ioctl or MARK_COMPRESSIBLE_WRITE ioctl. In case NVGPU_GPU_COMPBITS_GPU is requested through the ioctl PREPARE_COMPRESSIBLE_READ, CDE conversion command is not submitted and the output fence is cloned from the initial state fence (with syncpt_id=0). NvRmSyncWait on this fence from userspace lead to below error: 13e40000.host1x: nvhost_syncpt_wait_timeout: invalid syncpoint id 0 Initialize the buffer compbits state user fence syncpt_id to NVGPU_INVALID_SYNCPT_ID with nvgpu_user_sync_init() so that the userspace skips the NvRmSyncWait on that fence. While at it, initialize other uninitialized members, valid_compbits and zbc_color.
