Subject: [PATCH 1/2] Revert "rsi: fix potential null dereference in rsi_probe()"

This reverts commit f170d44bc4ec2feae5f6206980e7ae7fbf0432a0.

USB core will never call a USB-driver probe function with a NULL
device-id pointer.

Reverting before removing the existing checks in order to document this
and prevent the offending commit from being "autoselected" for stable.
