[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.
