[otp_ctrl] Disable assertion due to esc_en failure

This PR disables an assertion from `prim_arbiter_tree`. The assertion
tries to check if req should stay high until grant signal is set.
However, it does not work if `lc_escalate_en` signal is set.
Please feel free to discard this PR if you prefer some other ways to fix
it.
