Fix crash on CTS test:
dEQP-VK.robustness.robustness1_vertex_access.out_of_bounds_stride_30_middle_of_buffer
Bindings with multiple vertex attributes would not correctly detect
if the whole binding was remapped to new location/s. This meant
original binding's stride was never set to 0 which would report an
error and in some cases crash.
