btrfs: Consider system chunk array size for new SYSTEM chunks

Browse Source 
For SYSTEM chunks, despite the regular chunk item size limit, there is
another limit due to system chunk array size.

The extra limit was removed in a refactoring, so add it back.

Fixes: e3ecdb3fde ("btrfs: factor out devs_max setting in __btrfs_alloc_chunk")
