[PATCH 4/6] generic/765: Ignore mkfs warning

This test validates atomic writes for all possible block sizes. In ext4, for
smaller block sizes with configurations like:

export MKFS_OPTIONS="-O bigalloc,quota -b 65536 -C 131072"

The output can get corrupted with warnings like below because clustersize
more than 16xbs is experimental:

+ 16 times the block size is considered experimental

Hence pipe these to seqres.full to avoid false negatives.
