gs: avoid 6c type propagation / constant folding issue for set_cb_end()
6c changed "- cmd_lagest_size + 1" into a *unsigned* 32bit constant. which
got added to 64bit pointer making pcb->limit > pcb->end resulting
in errors for partial commands in the buffer. removing the parentesis
propagates the operation to 64bit.
