jbd2: On a __journal_expect() assertion failure printk "JBD2", not "EXT3-fs"

(cherry picked from commit 08ec8c3878cea0bf91f2ba3c0badf44b383752d0)

Otherwise it can be very confusing to find a "EXT3-fs: " failure in
the middle of EXT4-fs failures, and it makes it harder to track the
source of the failure.
