[XFS] kill the vfs_fsid and vfs_altfsid members in struct bhv_vfs

Browse Source 
vfs_altfsid was just a pointer to mp->m_fixedfsid so we can trivially
replace it with the latter. vfs_fsid also was identical to m_fixedfsid
through rather obfuscated ways so we can kill it as well and simply its
only user.
