btrfs: quit early if the fs has no RAID56 support for raid56 related checks
The following functions do special handling for RAID56 chunks:
- btrfs_is_parity_mirror()
Check if the range is in RAID56 chunks.
- btrfs_full_stripe_len()
Either return sectorsize for non-RAID56 profiles or full stripe length
for RAID56 chunks.
But if a filesystem without any RAID56 chunks, it will not have RAID56
incompat flags, and we can skip the chunk tree looking up completely.
