[PATCH 1/2] nvme: Update type from size_t to u16 for opts->queue_size

From: Nitesh Shetty
Date: Tue Nov 28 2023 - 22:03:44 EST


This fixes the smatch warning, "nvme_loop_create_ctrl() warn:
'opts->queue_size - 1' 18446744073709551615 can't fit into 65535
'ctrl->ctrl.sqsize'"
We don't need size_t for queue_size, u16 should serve the purpose,
as max size is limited to NVMF_DEF_QUEUE_SIZE(1024).
