Ming Lei b7803afc77 ublk: remove check IO_URING_F_SQE128 in ublk_ch_uring_cmd
commit 9c7c4bc986 upstream.

sizeof(struct ublksrv_io_cmd) is 16bytes, which can be held in 64byte SQE,
so not necessary to check IO_URING_F_SQE128.

With this change, we get chance to save half SQ ring memory.

Fixed: 71f28f3136 ("ublk_drv: add io_uring based userspace block driver")
