LU-2673 procfs: call lprocfs_free_xxx_stats() later

Defer calls to lprocfs_free_{obd,md}_stats() and
lprocfs_job_stats_fini() until after the corresponding proc entries
have been removed. Change the return of some proc fini()s to void.

LU-1812 ldiskfs: don't use sb->s_qf_inums

ext4-quota-first-class.patch was finally accepted into the mainline
Linux kernel via commit 7c319d32 (v3.6). The final version doesn't
include the cached inode numbers so they aren't available on newer
kernels that include this patch (or that are using an ldiskfs
patched using the usptream version).

Since the file system will refuse mounting when the inodes can't
be read, the lookup code isn't invoked without valid inode numbers
anyway.
