[PATCH v2] xfs/513: fix allocsize on archs with pagesize larger than blocksize

[PATCH v2] xfs/513: fix allocsize on archs with pagesize larger than blocksize

[Anthony Iliopoulos]

The minimum accepted allocsize mount option value is page size, which
causes the particular test to fail in architectures where page size >
block size. Fix it by basing the value on the platform page size rather
than the block size as obtained from mkfs. In addition add a filter so
that different values can be used without breaking the golden output.

Changes from v1 -> v2:

- renamed filter_pagesz to filter_xfs_opt
- renamed PAGE_SIZE to PAGESIZE
