Primvars is ignored when rendering basisCurves as bspline

[kreppene]

Describe the bug
When rendering BasisCurves using basis bspline, the primvars is ignored. and we get messages like this

/Root/RootOffset/g_geometry/groom/my_nice_groom/my_nice_groomShape: varying user-data count wrong! (found 651014 expected 550858) -- disabling user-data 'look_color'

/Root/RootOffset/g_geometry/groom/my_nice_groom/my_nice_groomShape: varying user-data count wrong! (found 651014 expected 550858) -- disabling user-data 'look_tip'

To Reproduce
Steps to reproduce the behavior:

1. Extract the attached zip file
2. Edit the .ass file and update the path to the usdfile (currently its pointing to my local harddriver)
3. kick -l ../shaders -l ../procedurals -l ../plugins C:/qvisten_pipeline/primvarsBug/renderme.ass

Expected behavior
If the primvars is working fine when rendering the BasisCruves using linear basis, it should also work when using bspline basis
