io_uring: add custom opcode hooks on fail
...
Sometimes we have to do a little bit of a fixup on a request failuer in
io_req_complete_failed(). Add a callback in opdef for that.

io_uring: conditional ->async_data allocation
...
There are opcodes that need ->async_data only in some cases and
allocation it unconditionally may hurt performance. Add an option to
opdef to make move the allocation part from the core io_uring to opcode
specific code.
Note, we can't just set opdef->async_size to zero because there are
other helpers that rely on it, e.g. io_alloc_async_data().

io_uring: move opcode table to opdef.c
...
We already have the declarations in opdef.h, move the rest into its own
file rather than in the main io_uring.c file.

io_uring: move poll handling into its own file
...
Add a io_poll_issue() rather than export the general task_work locking
and io_issue_sqe(), and put the io_op_defs definition and structure into
a separate header file so that poll can use it.
