1. Remove hipDeviceAttributePageableMemoryAccess checking as it is used to check xnack+ rather than fine-grained synchronization.
Note: hipHostMalloc() will alloc memory with fine-grained access and atomic by default when env HIP_HOST_COHERENT=1. For more information, see hip_programming_guide.
2. Fix some other bugs.
