[PATCH] i3c: master: renesas: Fix memory leak in renesas_i3c_i3c_xfers()

[Felix Gu]

The xfer structure allocated by renesas_i3c_alloc_xfer() was never freed
in the renesas_i3c_i3c_xfers() function. Use the __free(kfree) cleanup
attribute to automatically free the memory when the variable goes out of
scope.
