The compat_time_t type has been removed everywhere else,
as most users rely on old_time32_t for both native and
compat mode handling of 32-bit time_t.
Remove the last one in xfs.

As explained in https://www.spinics.net/lists/linux-xfs/msg35524.html
I've dropped the patch "xfs: disallow broken ioctls without
compat-32-bit-time" for this submission but will get to that later
when doing that as a treewide change.
Please apply these two for v5.6 in the meantime so we can kill off
compat_time_t, time_t and get_seconds() for good.

As a preparation for removing the 32-bit time_t type and
all associated interfaces, change xfs to use time64_t and
ktime_get_real_seconds() for the quota housekeeping.
This avoids one difference between 32-bit and 64-bit kernels,
raising the theoretical limit for the quota grace period
to year 2106 on 32-bit instead of year 2038.
Note that common user space tools using the XFS quotactl
interface instead of the generic one still use the y2038
dates.
To fix quotas properly, both the on-disk format and user
space still need to be changed.

This has a small conflict against the series at
https://www.spinics.net/lists/linux-xfs/msg35409.html
("xfs: widen timestamps to deal with y2038") which needs
to be rebased on top of this.
All other changes to remove time_t and get_seconds()
are now in linux-next, this is one of the last patches
needed to remove their definitions for v5.6.
If the widened timestamps make it into v5.6, this patch
can be dropped.

Not likely. :)
