[PATCH 2/2] generic/530: only use xfs-specific mkfs options when testing on xfs

["Theodore Ts'o" <tytso@mit.edu>]

This fixes a regression introduced by commit 000813899afb ("fstests:
scale some tests for high CPU count sanity") where this test
unconditionally tried to use the mkfs option "-l size=256m" which
would break when testing any file sytem other than xfs.

Fix this the same way commit 000813899afb dealt with this for
generic/531; so this was just an oversight.
