xfs: pass struct xfs_eofblocks to the inode scan callback

mainline-inclusion
from mainline-v5.13-rc4
commit 9d5ee837
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4KIAO
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9d5ee837595134f91bb2d66f571f498c3b8ab148

-------------------------------------------------

Pass a pointer to the actual eofb structure around the inode scanner
functions instead of a void pointer, now that none of the functions is
used as a callback.
