[PATCH 1/3] xfs: fix test mkfs.xfs sizing of internal logs that overflow the AG

["Darrick J. Wong" <djwong@kernel.org>]

From: Darrick J. Wong <djwong@kernel.org>

Fix a few problems with this test -- one of the things we test require
mkfs to run in -N mode, so we need to have a certain amount of free
space, and fix that test not to use -N mode.
