1. c/rm_stm: fixed returning incorrect max_collectible_offset …

   An off by one error in `rm_stm::max_collectible_offset` may lead to
   situation in which an stm couldn't continue. If `max_collectible_offset`
   returned last offset in the segment it may lead to the situation in
   which the whole segment was evicted before its last entry was applied.
   As the `max_collectible_offset` was returning `last_stable_offset` which
   indicates the offset for which all _previous_ offsets are decided (has
   no pending transactions and have been committed). In rare cases it may
   lead to situation where a segment ending at offset `n` was removed even
   though only `n - 1` was decided.
