exofs: Move exofs specific osd operations out of ios.c
ios.c will be moving to an external library, for use by the objects-layout-driver. Remove from it some exofs specific functions. Also g_attr_logical_length is used both by inode.c and ios.c move definition to the later, to keep it independent Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
