panvk: fix line-rasterization of bifrost

Vulkan defines the line rasterization to *always* use perpendicular
rather than aligned line ends (unless otherwise specified by
VK_EXT_line_rasterization). So let's remove the code that conditionally
sets the bit, we always want the default value (0) here.

It might seem confusing because we kinda named this field wrong. It's
really about perpendicular vs aligned line ends. That's a cleanup we
might want to deal with later, but deleting the assignment is sufficient
to fix this issue. This is also what we do for v10.

This was probably just copied from the Gallium-driver, where this logic
is more or less correct.
