[PATCH 3/5] xfs: don't assume preallocation is always supported on XFS

[Christoph Hellwig <hch@lst.de>]

The always_cow mode can't usefull preallocate space gіven that it always
has to write out of place, and thus will reject falloc or ioctl calls to
preallocate space in a file.  Add explicit checks for preallocation
support in various XFS-specific tests to support this.
