It seems that the 'unity_MatrixPreviousMI' get defined twice due to the Conditional compilation problem, try fix it with these steps:
1.Embeded 'com.unity.demoteam.hair' package;
2.Open 'HairVertex.hlsl' and comment line 26~28:

//#ifndef UNITY_SHADER_VARIABLES_INCLUDED
//float4x4 unity_MatrixPreviousMI;
//#endif

#ifndef UNITY_PREV_MATRIX_I_M
#define UNITY_PREV_MATRIX_I_M unity_MatrixPreviousMI
#endif

3.Problem solved (Temporarily).
