    libglusterfs/gfapi: set appropriate errno for inode_link failures
    
    We do not seem to be setting errno appropriately in case
    of inode_link failures. This errno may be used by any application
    (for eg., nfs-ganesha) to determine the error encountered. This
    patch addresses the same.
