Refactor __ublk_ch_uring_cmd to: - Have one function per operation instead of handling operations directly in the switch statement. - Mark most ublk_queue pointers as const. Given efforts to allow concurrent operations on one ublk_queue [1], it is important that ublk_queue be read-only (or accesses to it be properly synchronized) to avoid data races. This series is split off from [1]. No functional changes are expected.
