block: fix and cleanup bio_check_ro

commit 36585a4c813a1aa44fd5269db8b0339bde27b51b upstream.

Don't use a WARN_ON when printing a potentially user triggered
condition.  Also don't print the partno when the block device name
already includes it, and use the %pg specifier to simplify printing
the block device name.
