Previously we count all frostfs errors like:
ObjectNotFound, EACLNotFound
because frostfs status is unconditionally resolved into built-in go errors
but handleError method handled built-in errors like internal network ones.
Since after resolving frostfs errors status is also returned we start check this first
(cherry picked from commit 203bba65a0)
