xfs: rearrange code in xfs_inode_item_precommit

There are similar extsize checks and updates done inside and outside
the inode item lock, which could all be done under a single top
level logic branch outside the ili_lock. The COW extsize fixup can
potentially miss updating the XFS_ILOG_CORE in ili_fsync_fields, so
moving this code up above the ili_fsync_fields update could also be
considered a fix.

Further, to make the next change a bit cleaner, move where we
calculate the on-disk flag mask to after we attach the cluster
buffer to the the inode log item.
