Ming Lei b256795b36 ublk: handle UBLK_U_IO_PREP_IO_CMDS

This commit implements the handling of the UBLK_U_IO_PREP_IO_CMDS command,
which allows userspace to prepare a batch of I/O requests.

The core of this change is the `ublk_walk_cmd_buf` function, which iterates
over the elements in the uring_cmd fixed buffer. For each element, it parses
the I/O details, finds the corresponding `ublk_io` structure, and prepares it
for future dispatch.

Add per-io lock for protecting concurrent delivery and committing.
