[PATCH] fstests: generic/352 should accomodate other pwrite behaviors

[Bill O'Donnell <bodonnel@redhat.com>]

xfs_io pwrite issues a series of block size writes, but there is no guarantee
that the resulting extent(s) will be singular or contiguous. This behavior is
acceptable, but the test is flawed in that it expects a single extent for a
pwrite.

Modify test to accept any layout for the reflinked logical range.
