jfs: Update jfs_error

Use a more current logging style.

Add __printf format and argument verification.

Remove embedded function names from formats.
Add %pf, __builtin_return_address(0) to jfs_error.
Add newlines to formats for kernel style consistency.
(One format already had an erroneous newline)
Coalesce formats and align arguments.

Object size reduced ~1KiB.
