btrfs: open code and remove btrfs_inode_sectorsize helper

This is defined in btrfs_inode.h, and dereferences btrfs_root and
btrfs_fs_info, both of which aren't defined in btrfs_inode.h.
Additionally, in many places we already have root or fs_info, so this
helper often makes the code harder to read.  So delete the helper and
simply open code it in the few places that we use it.
