xfs: rename struct xfs_eofblocks

In the old days, struct xfs_eofblocks was an optional parameter to the
speculative post-EOF allocation garbage collector to narrow the scope of
a scan to files fitting specific criteria.  Nowadays it is used for all
other kinds of inode cache walks (reclaim, quotaoff, inactivation), so
the name is no longer fitting.  Change the flag namespace and rename the
structure to something more appropriate for what it does.

v2: separate the inode cache walk flag namespace from eofblocks
