BUG/MINOR: buffer: fix debugging condition in b_peek_varint()

The BUG_ON_HOT() test condition added to b_peek_varint() by commit
8873b85bd ("DEBUG: buf: add BUG_ON_HOT() to most buffer management
functions") was wrong as <data> in this function is not b->data,
so that was triggering during live dumps of H2 traces on the CLI
when built with -DDEBUG_STRICT=2. No backport is needed.
