misc: mempool: Fix bit mask value

SYS_MEM_POOL_KERNEL and SYS_MEM_POOL_USER are used by k_mem_pool flags
and should be defined as a bit mask.

It was defined as zero failing in all places checking for this
bit. e.g pool_irq_lock and pool_irq_unlock were not working correctly
because the check for this flag was always returning false.
