ext3: Unify log messages in ext3

Make messages produced by ext3 more unified. It should be
easy to parse.

dmesg before patch:
[ 4893.684892] reservations ON
[ 4893.684896] xip option not supported
[ 4893.684964] EXT3-fs warning: maximal mount count reached, running
e2fsck is recommended

dmesg after patch:
[  873.300792] EXT3-fs (loop0): using internal journaln
[  873.300796] EXT3-fs (loop0): mounted filesystem with writeback data mode
