iris: Fix constant buffer sizes for non-UBOs

Browse source 
Since the system value refactor, we've accidentally only been setting
cbuf->buffer_size in the UBO case, and not in the uploaded-constants
case.  We use cbuf->buffer_size to fill out the SURFACE_STATE entry,
so it needs to be initialized in both cases.

Fixes: 3b6d787e40 ("iris: move sysvals to their own constant buffer")
(cherry picked from commit 077a1952cc)
