[PATCH] xfsprogs: stop using off64_t in platform headers

[Christoph Hellwig <hch@xxxxxxxxxxxxx>]

Using off64_t may require special headers or compiler flags that aren't
always available, e.g. in the configure check in xfstests.  Rever to a plain
uint64_t to make apps compile as before.

While we're at it also rename the second argument of platform_discard_blocks
from end to len as that's what the BLKDISCARD ioctl excepts - we currently
always discard the whole device so it doesn't matter in practice.
