radeonsi/gfx9: fix crash building monolithic merged ES-GS shader
Forwarding from the ES prolog to the ES just barely exceeds the current maximum array size when 16 vertex attributes are used. Give it a decent bump to account for merged shaders having up to 32 user SGPRs. Fixes a crash in GL45-CTS.multi_bind.draw_bind_vertex_buffers.
