[PATCHv2] xfs/604: Make test as _notrun for higher blocksizes filesystem

["Ritesh Harjani (IBM)" <ritesh.list@gmail.com>]

If we have filesystem with blocksize = 64k, then the falloc value will
be huge (falloc_size=5451.33GB) which makes fallocate fail hence causing
the test to fail. Instead make the testcase "_notrun" if the initial
fallocate itself fails.
