arm: userspace: fix initial user sp location The initial user stack pointer gets rounded to STACK_ALIGN_SIZE, which can be much finer granularity than MPU regions. With certain stack size values passed to k_thread_create(), the stack pointer can be set past the defined region for the user thread's stack, causing an immediate MPU fault.
