LU-11667 tests: Fix sanity test 317 for 64K PAGE_SIZE OST

When create a file, blocks are allocated with PAGE_SIZE aligned,
see function osd_ldiskfs_map_inode_pages(). E.g. for 64K PAGE_SIZE
Arm64 OST server, if create a file with size less than 64K, it
actually allocates 128 blocks each block 512 Bytes.

It needs to adjust the test for 64K PAGE_SIZE OST server.
