xfs: only check the superblock version for dinode size calculation

Browse Source 
commit e9e2eae89ddb658ea332295153fdca78c12c1e0d upstream.

The size of the dinode structure is only dependent on the file system
version, so instead of checking the individual inode version just use
the newly added xfs_sb_version_has_large_dinode helper, and simplify
various calling conventions.
