xfs: fix tests to handle removal of no-alloc create nonfeature

We're removing from XFS the ability to perform no-allocation file
creation.  This was added years ago because some customer of SGI
demanded that we still be able to create (empty?) files with zero
free blocks remaining so long as there were free inodes and space in
existing directory blocks.  This came at an unacceptable risk of
ENOSPC'ing midway through a transaction and shutting down the fs, so
we're removing it for the create case having changed our minds 20
years later.

However, some tests fail as a result, so fix them to be more
flexible about not failing when a dir/file creation fails due to
ENOSPC.
