[XFS] kill xfs_iocore_t
xfs_iocore_t is a structure embedded in xfs_inode. Except for one field it just duplicates fields already in xfs_inode, and there is nothing this abstraction buys us on XFS/Linux. This patch removes it and shrinks source and binary size of xfs aswell as shrinking the size of xfs_inode by 60/44 bytes in debug/non-debug builds.
