drm/ast: Fix invalid usage of AST_MAX_HWC_WIDTH in cursor atomic_check
[ Upstream commit ee4a92d690f30f3793df942939726bec0338e65b ]
Use AST_MAX_HWC_HEIGHT for setting offset_y in the cursor plane's
atomic_check. The code used AST_MAX_HWC_WIDTH instead. This worked
because both constants has the same value.
