xfs: fix type mismatches in the inode reclaim functions

mainline inclusion
from mainline-v5.14-rc1
commit 10be350b
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=10be350b8c6c426b82d4df937f25b37eabdc3d67



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

It's currently unlikely that we will ever end up with more than 4
billion inodes waiting for reclamation, but the fs object code uses long
int for object counts and we're certainly capable of generating that
many.  Instead of truncating the internal counters, widen them and
report the object counts correctly.
