radeonsi: fix dvec[34] attributes sourced from current attribute state
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: 9b91e0b54cc2 ("radeonsi: allow unaligned vertex buffer offsets and strides on CIK-VI")
