[ Upstream commit 4e00422ee62663e31e611d7de4d2c4aa3f8555f2 ]
The block size stored in the super block is used by subsystems outside of btrfs and it's a copy of fs_info::sectorsize. Unify that to always use our sectorsize, with the exception of mount where we first need to use fixed values (4K) until we read the super block and can set the sectorsize.
Replace all uses, in most cases it's fewer pointer indirections.
