bsg: add io_uring command support to generic layer
Add an io_uring command handler to the generic BSG layer. The new
.uring_cmd file operation validates io_uring features and delegates
handling to a per-queue bsg_uring_cmd_fn callback.
Extend bsg_register_queue() so transport drivers can register both
sg_io and io_uring command handlers.
