msm: kgsl: Pass correct buffer size for mapping gpuobj user memory



Current code incorrectly specifies buffer size as 0 for mapping
gpuobj user memory. This causes the map to fail because buffer
size is expected to be a non zero value. Fix this by passing the
correct size of the buffer to be mapped.
