radeonsi: fix dvec[34] attributes sourced from current attribute state

Browse source 
The state tracker no longer uploads those attributes for us,
so we must conservatively upload the size of the largest
attribute, which is a dvec4.

Fixes a regression of GL45-CTS.gpu_shader_fp64.varyings and
GL45-CTS.vertex_attrib_64bit.limits_test.

Fixes: 9b91e0b54c ("radeonsi: allow unaligned vertex buffer offsets and strides on CIK-VI")
