libext2fs: revert "try to always use PUNCH_HOLE for unix_discard"

Revert bcca9876a3428c10417c660b78933e6e70e8a5f5, because
fallocate(PUNCH_HOLE) on block devices was changed to use zeroout
instead of discard shortly after block device fallocate was merged.
zeroout isn't necessarily a "drop storage" operation like discard is,
so we prefer to use that on block devices.
