d2b7fa6174 io_uring: Remove unnecessary BUILD_BUG_ON
In the io_uring_cmd_prep_async() there is an unnecessary compilation time
check to check if cmd is correctly placed at field 48 of the SQE.

This is unnecessary, since this check is already in place at
io_uring_init():

          BUILD_BUG_SQE_ELEM(48, __u64,  addr3);

Remove it and the uring_cmd_pdu_size() function, which is not used
anymore.
