Alexander Motin b1ccab1721 ARC: Avoid overflows in arc_evict_adj() (#17255)
With certain combinations of target ARC states balance and ghost
hit rates it was possible to get the fractions outside of allowed
range.  This patch limits maximum balance adjustment speed, which
should make it impossible, and also asserts it.

Fixes #17210
