fsx: fix errors due to unsupported FIDEDUPERANGE

Older kernels (prior commit 494633fac7896 "vfs: vfs_dedupe_file_range()
doesn't return EOPNOTSUPP") will return EINVAL when operation is not
supported. Make fsx treat this error as a sign of unsupported
deduplication as well to make it usable with these older kernels.
