[Mesa-dev] [PATCH] mesa: fix texStore for FORMAT_Z32_FLOAT_S8X24_UINT

From: Jiadong Zhu <Jiadong.Zhu at amd.com>

_mesa_texstore_z32f_x24s8 calculates source rowStride at a
pace of 64-bit, this will make inaccuracy offset if the width
of src image is an odd number. Modify src pointer to int_32* as
source image format is gl_float which is 32-bit per pixel.
