Reduce ARC fragmentation threshold

Description

Reduce ARC fragmentation threshold

As ZFS can request up to SPA_MAXBLOCKSIZE memory block e.g. during zfs recv,
update the threshold at which we start agressive reclamation to use
SPA_MAXBLOCKSIZE (16M) instead of the lower zfs_max_recordsize which
defaults to 1M.
