io_uring: use the text representation of ops in trace 

It is annoying to translate opcodes to textwhen tracing io_uring. Use the
io_uring_get_opcode function instead to use the text representation.

A downside here might have been that if the opcode is invalid it will not
be obvious, however the opcode is already overridden in these cases to
0 (NOP) in io_init_req(). Therefore this is a non issue.
