ac: fix build error in si_shader

assert() is replaced by unreachable(), to avoid following building error:

external/mesa/src/gallium/drivers/radeonsi/si_shader.c:1967:1:
error: control may reach end of non-void function [-Werror,-Wreturn-type]
}
^
1 error generated.

Fixes: c797cd6 ("ac: add load_patch_vertices_in() to the abi")
