panfrost: Allocate shared memory in OpenCL

In OpenCL, we can have no shader-defined shared memory but some dispatch-time
variable memory. This is not reflected in ss->info.wls_size, so check the right
variable instead so we allocate the appropriate memory.

Fixes page faults accessing shared memory with Rusticl, e.g. in the vstore_local
test.
