iris: clear bos_written when resetting a batch

This fixes dEQP-EGL.functional.sharing.gles2.multithread.* tests that
are hitting: "iris: Failed to submit batchbuffer: Invalid argument"
error.

v2: clear on reset rather than clear 'on-the-fly' (Kenneth Graunke)

Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/5537
Fixes: e4c3d3efc7a ("iris: Defer construction of the validation (exec_object2) list")
