[PATCH 4/7] engines/io_uring: simplify io_u_free

Just free the buffer unconditionally. If the pointer is null nothing
will happen, so no harm is done.

This lets us also use this function for the io_uring ioengine when it
gains the ability to handle metadata which will happen in a subsequent
patch.

No functional change intended.
